"Some say the moral failing at the heart of market triumphalism was greed, which led to irresponsible risk-taking. The solution, according to this view, is to rein in greed, insist on greater integrity and responsibility among bankers and Wall Street executives, and enact sensible regulations to prevent a similar crisis from happening again.
This is, at best, a partial diagnosis. While it is certainly true that greed played a role in the financial crisis, something bigger was and is at stake. The most fateful change that unfolded during the past three decades was not an increase in greed. It was the reach of markets, and of market values, into spheres of life traditionally governed by nonmarket norms. To contend with this condition, we need to do more than inveigh against greed; we need to have a public debate about where markets belong—and where they don’t."
