You got T.L and we are nearly there. About 50% of the population has no Federal tax obligation. I know its not exactly the same thing but its close.
I’ve heard Rush and many economists say the the top ten percent of wage earners pay more than 60 percent of all federal income taxes. This doesn’t include payroll taxes but Obama promises to correct that - by eliminating the income cut-off on them. In other words, by RAISING them for everybody! What else can you expect from someone the National Journal rated the most liberal member of the Senate and who is even to the left of the socialist Bernie Sanders of Vermont!!?
