In my opinion, the seeming inevitability of Orszag-like migrations points to a potentially fatal tension within the progressive strand of liberal thought.
Progressives laudably seek to oppose injustice by deploying government power as a countervailing force against the imagined oppressive and exploitative tendencies of market institutions. Yet it seems that time and again market institutions find ways to use the government's regulatory and insurer-of-last-resort functions as countervailing forces against their competitors and, in the end, against the very public these functions were meant to protect.
We are constantly exploited by the tools meant to foil our exploitation. For a progressive to acknowledge as much is tantamount to abandoning progressivism. So it's no surprise that progressives would rather worry over trivialities such as campaign finance reform than dwell on the paradoxes of political power. But it really isn't the Citizens United decision that's about to make Peter Orszag a minor Midas. It's the vast power of a handful of Washington players, with whom Mr Orszag has become relatively intimate, to make or destroy great fortunes more or less at whim.
