While I agree with most of your points (Bill Gates probably comes under the AMT) I would much prefer a complete overhaul of the tax system rather than more tinkering around with the Rube Goldburg tax laws that we now have. I would favor a modified flat tax, but would be open to other ideas.
From the spending side, I would like to eliminate transfer payments to state and local governments, where the Federal government taxes everybody only to send the money (less a large bureaucratic fee) back to the states - why not let the states handle their own taxation? Why is the Federal government supporting so many projects that are not in its purview under the Constitution?
Like I said earlier, it would probably take a revolution.
