Which one, Paul?

Paul Krugman in the New York Times (1.4.05):

When benefit payments start to exceed payroll tax revenues, Social Security will be able to draw on that trust fund. And the trust fund will last for a long time: until 2042, says the Social Security Administration; until 2052, says the Congressional Budget Office; quite possibly forever, say many economists, who point out that these projections assume that the economy will grow much more slowly in the future than it has in the past.

Paul Krugman in the New York Times (2.1.05):

Schemes for Social Security privatization, like the one described in the 2004 Economic Report of the President, invariably assume that investing in stocks will yield a high annual rate of return, 6.5 or 7 percent after inflation, for at least the next 75 years. Without that assumption, these schemes can't deliver on their promises. Yet a rate of return that high is mathematically impossible unless the economy grows much faster than anyone is now expecting.

I don't agree with Bush's plan: the system needs to be abolished, not amended. However, Krugman is guilty of the same duplicity as the Bush administration.
