Why are rich people stupid?

Kevin Drum notes that Walmart is suffering because it's customers don't have any money to spend. Less food stamps, loss of long-term unemployment insurance, shrinking value of the minimum wage, continued high unemployment due to austerity . . . Their sales and profits are down and so is their stock price.

Well now I wonder whose fault that is? Hmm. Could this have anything to do with it?

The Walmart Political Action Committee spent more than $2 million influencing federal elections in three of the last five federal election cycles, according to a report released Tuesday by Making Change at Walmart, a group of advocates, Walmart workers and others aimed at transforming the company. The report also said that members of the Walton family, the billionaire heirs to the Walmart fortune who own over half of Walmart common stock and hold three seats on the company's board, spent more than $1.3 million on federal elections last year, along with hundreds of thousands more at the state and local level. . . . .

In the case of both the Walmart PAC and the Walton family, much of their spending has gone to candidates supporting conservative causes, the report found.

Go figure. But make sure you don't use any of that fuzzy math with letters in it.
