Fair = tax everybody. Don’t pay the working poor to not pay taxes.
How many years did we kick around the idea of a “fair tax”? As I understood that, everyone paid the same percentage of their income—whatever it was.
That still seems to me to be the most equitable/efficient way of taxing the population. No long forms to file, no deductions, no lawyers, just pay a percentage of your income that everyone else pays.
This would still be taxing the rich more, as the more you earn, the more you pay, but you pay the same percentage as everyone else.
