a facebook conversation about capitalism
***this post is pursuant to one i hope to write soon concerning something in the way of a reflection on our changing world, and the implications of these perceived changes for my generation. in the meantime, here's what i hope is a somewhat intelligible defense of markets***
---
these are some heart-felt, well-spoken reflections, all, thanks for sharing. i've been putting off writing something of my own in the way of a reflection on our times, but for now i'll settle for a comment or two:
at the risk of sounding like an economist, i tend to think that markets are generally good things: millions of people deciding individually what they need/want and what they would like to pay creates a huge market from producers of goods and services looking to make money by providing for those needs. organizations that are particularly effective at doing this (e.g. WalMart) do become enormously rich and powerful, though, and i think it's reasonable to worry about the corrupting influences that power and profit motive may have on the decisions of these firms. Furthermore, markets don't provide for everything, like schools, public infrastructure, and firemen. So the people need a strong advocate to (a) make sure that the markets function impartially with respect to all participants, including the biggest players (that's what the FTC exists for: shttp://arstechnica.com/tech-policy/news/2011/06/ftc-launching-antitrust-probe-over-google-search-ad-businesses.ars) and (b) that our common interests not provided for by the market will be looked after. 'Capitalism' refers to a system of economic management whereby those who control/acquire productive assets (machinery, money, an innovative idea) put them to use in ways that meet a demand of the market, often making the managers extremely wealthy. As an example, take Facebook and any of the several companies who make the computers we're using to have this exchange: Mark Zucherberg and the folks at Lenovo won from pushing these products in a MUCH bigger way than any of us did. But that's because they gave each of us something that we value a lot: access to information and computing power. Within the right parameters, I think it's a good deal.
So what are we concerned about? In theory this whole thing sounds great, but we know from looking around us that the wealthy do often run roughshod over the poor, that corporate power is not always restrained, and that the growing wealth gap in our nation seems at odds with the notion of america as a place where, whatever 'fifth' you’re in, initiative and perseverance can be your ticket to a better life. I'm worried, too, but I'm less confident that the solution is a wholesale rejection of capitalism or a corporate boycott of WalMart. To chase that particular example, consider why so many people shop at WalMat: because it's cheap. And why does that matter? Because a lot of folks are tight on cash. So if enough of us boycott WalMart and bring it down, what happens to the people who rely on it for clothes and day to day staples? Their cost of living goes up, and our anti-corporate hubris is vindicated at the expense of those less fortunate than ourselves. There's also decent evidence that WalMart leverages its enormous influence in the market for good ends. See: http://business-ethics.com/2010/05/15/1411-assessing-walmarts-environmental-impact/. for controversial but well-argued piece by paul krugman regarding labor conditions in the third world see: http://www.slate.com/id/1918/. in spite of its failings, i think that a market is a better system than the alternatives human societies have tried so far.
time to wrap this up. as Thabisile, quoting Ghandi, said: 'be the change you wish to see.' What kind of change do i wish to see? i wish that business leaders were innovative and ambitious, but more compassionate and less driven by greed. i wish our politicians were more courageous, willing to lay their offices on the line for the sake of promoting policies they actually believe in. i wish more parents hung in there with respect to their marriages and children. so what kind of man am i going to be, and what will be my contribution? what about you? the economy we live in is changing along with our times, and one of these days i hope to sit down and think it all through for a while. One thing is certain, though: women and men of strong character, determined to act with mercy, courage, and integrity, are need now as much as, if not more, than ever before.

a longer road ahead
Upon reflection, what at first had the disheartening impact of a shifting goal post looks like a blessing. I don't have the luxury of complacence--a luxury that so frequently has a toxic affect on our sharpness of the mind, softness of the heart, and strength of spirit.

so that's where this craziness began...
So it occurred to me tonight, as I was biking home from watching a panel of a Muslim, a Jew, and a Christian talk about religion in the public square, that my dad would frequently share a bit of thinly-veiled statistical wisdom with me as a boy. "Aaron, what's the probability that if you flip a coin 10 times and it comes up heads every time, that the next flip will be tails?" "Mmmmmmm, I don't know," I would say, as kids who aren't quite sure where their parents are "going with this" do. "Exactly the same!" my dad would say with a gleam in his eye and that little boy's grin that he still has today when he gets excited about something (probability theory?!). How incredible that, in spite of all that past baggage, all those failed attempts to be tails, an evenly-weighted coin had a clean slate, a 50% CHANCE, to be tails at each new trial.
"Wait a minute," I thought, "something about this seems fishy..." But of course I was still learning to do things that I still struggle with today, like basic arithmetic, multiplication by 11, and spelling, so I just let that sense of unease percolate in the back of my brain. Day, after day, after day. And only now, after stomping off on this wild goose chase of a degree, am I able to frame the issue more clearly. You see, it's a very simple question of joint versus individual trials involving an outcome that can only take one of two values. As it turns out, the probability of flipping a coin 11 times and only observing tails on the 11th flip is (almost) exactly 1/2048, even if the probability of each individual flip attaining that outcome is constant at 1/2. Remember that, guys: joint trials of independent events tend to be less probable than the aggregated individual outcomes of which they are composed. There's some real life-directing wisdom in this, so use your imagination and reach for it.
But where I was going with all this is to say that it's your fault, dad, that the muddled fascination (or perhaps confusion) with mathematical quantification of uncertainty that you planted in my brain 17-odd years ago drove me into this masochistic choice of degree here at Oxford. Which is, of course, my back-handed way of saying that I am in awe of your fascination with the world and deeply grateful for all that your sense of wonderment, especially in things as simple as a coin flip, has contributed to the odd character I am today.
Thinking of coins and campfires as I write time series models and wrestle with spatial statistics tonight,

home(?) again
I spent most of the day after arriving back in Cape Town from Zim with Matthew before rejoining my crew at the Zebra Crossings hostel. As alluded to in the last post, the time with my cousin was very significant relationally. It was an enormous blessing to learn a bit about this person who I've always looked up to from a distance, but with whom I'd never moved much beyond casual conversation. Matthew is sincere, warm-hearted, and well-spoken, and as we talked about everything from life goals and relationships to favorite beers I felt that we connected as friends. It was also good to speak about our common side of the family: where we come from shapes who we are, and over the course of the trip I was filled once again with deep appreciation for the extraordinary trials that my father and his sisters braved to become the caring, accomplished, intellectually-alive people that they are today. Polhami are strange folk, as well, and we spent about as much time joking about our foibles as reflecting on our trials.
The rest of the time in Cape Town was filled with more good things: trips to the townships, including lunch at Mzoli's in Guguletu after church, touring Robben Island, where Nelson Mandela wrote "Long Walk to Freedom" during his long tenure or imprisonment, and visiting an election day rally during a pitstop on a road trip to Knysna. We also had the honor of meeting Desmond Tutu the day before last Wednesday's elections. This remarkable man was the first black Archbishop of Cape Town, chaired the Truth and Reconciliation Commission in post-Apartheid South Africa, and is a renowned advocate of peace and justice in the world. He recently came under fire from many of his colleagues when he denounced Jacob Zuma, head of the ANC and soon-to-be president of South Africa, as unfit to lead. The ANC and its founding fathers led South Africa to freedom, yet the party has been wracked by corruption and fraud in recent years, and many argue its leadership has been inept in meeting the country's most pressing challenges. Jacob Zuma--who has claimed that cold showers prevent HIV transmission and just recently succeeded in having charges of money laundering in a multi-billion dollar arms deal dropped on procedural grounds--represents the worst of what the ANC has to offer in the eyes of many South Africans. Though Tutu expressed no desire to see the ANC voted out of power, his hope was that the minority opposition parties could rally to prevent it from obtaining the two thirds majority necessary to unilaterally amend the constitution. Dissenting voices are essential to functioning of healthy democratic institution, and Tutu's view was that the ANC had grown lazy and corrupt over the course of its unchallenged stay in power.
But this little diversion into politics distracted me from what I wanted to say about the man himself. At age 77 he shows his age a little bit, yet his quick laugh, bright smile, and self-demeaning sense of humor reveal a warm and gentle spirit that has not hardened through years of trial. It was humbling to sit in the presence of this man, who three weeks earlier I had watched break down weeping on film as he listened to one of his African brothers describe how he had been tortured under apartheid. As we sat down together in his office he said "let us begin with a prayer," and invited the Holy Spirit to come and animate our hearts, giving us joy and inspiring us to love one another as Christ first loved us. That place in his heart where God's spirit dwells is the secret of the man's charisma, and though his political perspectives were helpful it was simply seeing his joyful spirit that moved me the most.
As in Rwanda, the limited amount of time spent with community leaders and servants in South Africa affirmed my belief that what the world needs more than anything else is men and women who are alive in their gifts, and having oriented their lives around a purpose beyond their own gratification. I met a lot of people in South Africa who exemplify this, and challenge me to consider whether I am doing the same. I believe that the most fulfilling purpose around which an individual life can be oriented is Christ, yet I am convinced that God smiles all of those who strive to live fully, sincerely, and selflessly, partnering together through his Spirit to bring about a renewed creation. And lofty theological musings aside, people like Desmond Tutu, Edwin Cameron, Lindela, Kanisua, Sindatenda from BEEP are incredible because they are down-to-earth, joyful, passionately-committed people who give more to their communities than they take.
Big words. Words come easy. The nagging question in the stillness and quiet of a lazy Sunday morning, though, is whether I live this way. Here, back at Oxford, exams a month away, I continue to pray for wisdom to make the most of this time, and for a heart that desires to do justice, love mercy, and walk humbly with God in the world.
