1) What rate will they start at?
2) Who is to stop them from raising each year?

Flat tax is a shell game as far as I am concerned.
I thought I read that total U.S. payroll is around $25 trillion? If so, then the federal government can live on 10% across the board, no exceptions, no deductions, everyone pays (you earn $1000/yr., pony up $100.), constitutional amendment to that effect.
