DEAN BAKER: Mr. Arithmetic will save Social Security. Mr. Baker may have passed third-grade arithmetic, but it's clear that his math skills stopped there. If you follow 'Mr. Arithmetic' (not obvious) then it's clear that Baker's political leanings are Marxist (from each according to his ability, to each according to his need) and his intellectual skills (scroll through his other posts) are about on a par with my three cats.

[Added: my wife thinks I'm insulting the cats. Apologies to Diamond, Daisy, and Shadow.]
