How about just a flat income tax of 5% for everyone?
And hget rid of 95% of government programs.
I bet you didn't know that graduated income taxes are straight out of Marx and Engels' "Communist Manifesto".
That would work to eliminate tax planning but not enough to fund our current beast. I personally believe that 5-6% is about the max that people would pay without taking serious steps to avoid it. If it were ever passed I'd be able to make tons of money helping clients invest and make their business more profitable. It would be great.
