DAILY KOS CAN'T DO MATH. Or can't read, I'm not quite sure which. In a post keying on the Social Security debate, diarist Joan McCarter makes this claim:

[Caremark CEO Larry] Merlo has a retirement fund of $46 million, and if he invested that in an annuity starting at age 65, he'd get $263,169 a month for life. If he took Social Security, too, he'd get $267,445 a month.

The figure $263,169 is a bit high, but roughly on the mark, since a single-life annuity at age 65 generally pays between 6% and 6.2%. But the Social Security amount, $4,276 [$267,445-$263,169] is wildly off the mark, since as a simple Google search will show, the maximum Social Security benefit payable to anyone retiring at age 65 in 2013 is $2,513/month. It's also taxable.

Time for the Kos Kidz to go back to school.
