I answered your question. Tax rates should go back to what they were in the 50s and 60s, and most successful time. I pasted the information above.
Through, as I mentioned, what constitutes wealthy should be somewhat dependent on cost of living of the area.
This is a theory many of us on the right are aware of, and many on the left are not, or if they are, hate it. It's called action/ reaction
If we all decided to meet at a bar one night, and I reached out to shake your hand, it's likely you would return the gesture. This is positive action--positive reaction.
However if we met and I pushed you into the wall, it's likely you would push me into the wall right back. Negative action--negative reaction.
At most any time, an action is met with a similar reaction. If you try to take most all of the money from the wealthy, are you really expecting a positive reaction????
If the tax rate were 0%, the government would collect 0 dollars. If the tax rate were 100%, the government would still collect 0 dollars because who would be stupid enough to produce wealth?
