Forbes has two articles responding to Warren Buffett's call for higher taxes.
Daniel Shuchman gives well documented example after well documented example of tax considerations factoring into Mr. Buffett's business moves as Mr. Buffett himself described them at the time. Mr. Shuchman also observes, "Buffett's sanctimonious tone is inversely proportional to his willingness to propose any reform that would materially impact his own financial position."
Jerry Bowyer reminds us that before Mr. Buffett became a tax-increaser he flirted with the nuclear freeze and population control movements, and suggests that the left-wing politics was Mr. Buffett's way of rebelling against his parents.
