Social Security Privateers Rely on Innumeracy

I can't believe that we need an economics Ph.D. like Paul Krugman to point this out:

This week, in a closed meeting with African-Americans, Mr. Bush asserted that Social Security was a bad deal for their race, repeating his earlier claim that "African-American males die sooner than other males do, which means the system is inherently unfair to a certain group of people." In other words, blacks don't live long enough to collect their fair share of benefits....

Mr. Bush's argument goes back at least seven years, to a report issued by the Heritage Foundation - a report so badly misleading that the deputy chief actuary (now the chief actuary) of the Social Security Administration wrote a memo pointing out "major errors in the methodology." That's actuary-speak for "damned lies."

In fact, the actuary said, "careful research reflecting actual work histories for workers by race indicate that the nonwhite population actually enjoys the same or better expected rates of return from Social Security" as whites.

Here's why. First, Mr. Bush's remarks on African-Americans perpetuate a crude misunderstanding about what life expectancy means. It's true that the current life expectancy for black males at birth is only 68.8 years - but that doesn't mean that a black man who has worked all his life can expect to die after collecting only a few years' worth of Social Security benefits. Blacks' low life expectancy is largely due to high death rates in childhood and young adulthood. African-American men who make it to age 65 can expect to live, and collect benefits, for an additional 14.6 years - not that far short of the 16.6-year figure for white men.

Second, the formula determining Social Security benefits is progressive: it provides more benefits, as a percentage of earnings, to low-income workers than to high-income workers. Since African-Americans are paid much less, on average, than whites, this works to their advantage.

Finally, Social Security isn't just a retirement program; it's also a disability insurance program. And blacks are much more likely than whites to receive disability benefits.

Put it all together, and the deal African-Americans get from Social Security turns out, according to various calculations, to be either about the same as that for whites or somewhat better. Hispanics, by the way, clearly do better than either.

By assuming that every statistical outcome is the same as the mean outcome Bush and his friends rely on the ignorance of Americans in math and statistics

Incidentally, William Dembski relies similarly on the innumeracy of his audience and is a bit less honest about, in my opinion (see here and here.)

Yep. The Social Security "reform" and "intelligent" "design" crowds use the same lack of reasoning.
