Heh, I asked this question a while ago. Here's a list someone on the board gave me:
The government gets about 40% of its money, or 800$ billion each year, from the income tax. Ron Paul proposes eliminating all 700 foreign military bases, which costs 1,000 billion each year. Even if we cut the income tax right now, we will still earn about the same amount of money as we did in year 2000, because the main reason the government has expanded so much over the past few years is because of George Bush’s ineffective programs and policies (Department of Homeland Security, No Child Left Behind, Patriot Act, Department of Education, Department of Commerce)
Here is where the other 60% of the government money comes from:
1. Sales tax
2. DMV fees
3. Tobacco Tax
4. Corporation Tax
5. Liquor Tax
6. Insurance Tax
7. Highway Users Tax
8. Custom Duties
9. Gas Tax
10. Death tax
11. Fringe Benefits Tax
12. Petroleum Resource Rent Tax
13. PRINTING MONEY!!! (Inflation tax)
14. Lottery tickets
15. Debt Consolidation Loans (The government taxes the poor too...)
16. Hundreds of "pollution" dis-incentives
17. Capital Gains Tax
18. Foreign Loans (I think it's something like 1/10000 of what's loaned to us by Foreigners)
19. Interest on Fed Funds
20. Selling/renting/selling-construction-rights of Government owned land.
