Social Security follies - Matt Hoy: "Of course, if you’ve pledged to lower taxes on the bottom 95 percent of Americans, then you can only increase taxes on the top 5 percent - and there’s not enough money in the top 5 percent to make Social Security solvent even if you took all of it."

I like how Obama is going to "ask" people making over a quarter-mil to "pay a little more into the system." Isn't that polite? Much more from Harvard economist Greg Mankiw.
