A flat tax would, for one, put out of business a new class of worker, the white collar cpa, according to many.... This is the problem with congress, they will never suffer by their actions. Ten years and they get a pension of 6 figures, free health care for life, and millions in perks along the way.... Term Limits, no pension, no free anything should be the rule.
A flat tax on ALL income would increase revenues without question. It would also eliminate the IRS. I mean, with no child left behind, we should be able to figure out 6% or 15% of something.....
Most of the proposals I've seen are 17% with deductions for home mortgages and healthcare.
