Put it this way: we have just finished the first American business cycle ever, the first since British settlers landed at Jamestown and promptly began dying of malaria, the first ever in which median household incomes did not grow from peak to peak.
How much of the blame for poor performance in this century can be laid at the door of the George W. Bush administration is an active research question. Government surpluses rather than the Bush deficits would have given us a lower dollar, more exports, faster growth of production in sectors which may well have powerful external benefits, and a more equal income distribution. Median household income would have done better. How much better? Give me a couple weeks to solidify my view.
But I have not found anybody not completely corrupt still willing to say that Bush economic policies have been on net a plus for America.
