Here's my ideal income tax plan. I wanted to make the highest bracket begin at $500K, but couldn't get it to work, so used $750K instead, which I think is still reasonable:

1. Abolish or drastically reduce the estate/inheritance tax
2. Lower corporate tax rate to 15%
3. Remove loopholes and deductions that disproportionately favor wealthy taxpayers and/or corporations
4. Increase federal cigarette tax to $2 per pack and extend to all tobacco products
5. Increase all federal alcohol taxes
6. Institute "environmental sin tax" based on sustainability of goods (including tariffs) and provide tax incentives for sustainable development
