The Schizophrenia of Economic Populism

In his lede to set up a different topic, George Will utilizes this story about Sen. Barack Obama, from the campaign trail:

Sen. Barack Obama recently told some Iowa farmers that prices of their crops are not high enough, considering what grocers are charging for other stuff: “Anybody gone into Whole Foods lately and see what they charge for arugula?”

Want to bet that Sen. Obama’s plan to get the prices of crops higher will involve some form of government subversion of economics? Want to also bet that he’ll campaign against the Whole Foods merger because it leads to higher prices? How about the possibility (probability?) that he’ll promise to help working families who have trouble paying their weekly grocery bills?
