I take exception to Thomas Schaller's assertion that "Overhead in federal insurance programs like Medicare and Social Security is minimal. By some estimates, only 2 percent of expenditures go to administrative overhead" ("Sure, government is flawed – but markets are too," May 16).
My wife formerly worked in the Social Security Administration, and she says Mr. Schaller's arguments are way off the mark. "By some estimates?" How vague is that? Why doesn't The Sun require the learned professor to cite his sources?
