Jeffrey Friedman writes,
What I am calling social democracy is, in its form, very different from socialism. Under social democracy, laws and regulations are issued piecemeal, as flexible responses to the side effects of progress — social and economic problems — as they arise, one by one. (Thus the official name: progressivism.) The case-by-case approach is supposed to be the height of pragmatism. But in substance, there is a striking similarity between social democracy and the most utopian socialism. Whether through piecemeal regulation or central planning, both systems share the conceit that modern societies are so legible that the causes of their problems yield easily to inspection. Social democracy rests on the premise that when something goes wrong, somebody — whether the voter, the legislator, or the specialist regulator — will know what to do about it. This is less ambitious than the premise that central planners will know what to do about everything all at once, but it is no different in principle.
The whole piece is very consistent with my views on the financial crisis, regulation, and the discrepancy between the knowledge that policy makers are implicitly assumed to hold and their actual level of ignorance.
