Flat income tax retains business taxes - you know, the ones we pay for in higher prices, lower wages, or reduced ROI. IE hidden taxes.
Oh yeah, the flat income tax retains payroll taxes in addition to income taxes - it retains payroll taxes for employee AND employer.
The nrst is a flat tax on spending, not income.
I'm in favor of a flat tax, and not a percentage based flat tax either. a set amount flat tax, like say $500 for each and every person. That's it. No business tax, No retail tax.
