Tax Cut for Teachers:New York Times Columinist Thomas Friedman

Thomas Friedman of The New York Times wants teachers to be even more powerful:

One of the smartest stimulus moves we could make would be to eliminate federal income taxes on all public schoolteachers so more talented people would choose these careers.

Of course Thomas Friedman is married to a teacher so he'd benefit.Anyway,why are public school teachers more deserving of tax cuts than anyone else?
