Who’s providing the real value in our economy? Quiggin argues that we shouldn’t be ready to dismiss the idea of dramatically shrinking the financial sector, which now makes up more than 20 percent of the U.S. GDP:

I’d like to look at a specific question raised by the discussion of private returns and social value, namely: can Wall Street, in its present form, be justified? That is, does the share of income flowing to corporations and professional workers in the financial sector reflect their marginal contribution to the total value of social output, so that, if their work ceased to be done and their skills were allocated elsewhere, we would all be worse off?

I argue that society as a whole would be better off if the financial sector were smaller, and received much smaller returns. A political strategy based on cutting the financial sector down to size has more promise for the Left than any alternative approach now on offer, and is a necessary precondition for a broader attempt to make the distribution of wealth and power more equal.
