I don't want to be president. I can't be president. Only a crazy person would want to be president.
BUT- if I were president, I would change how we do income taxes in this country.
First- there would be no filing of taxes every year. It's such a waste of time. Your employer would take your taxes up front and that would be it. The only folks who would have to file would be ones who get tips or work as freelancers. This means we wouldn't need the IRS except for maybe a dozen agents. The rest would have to find legitimate careers. Saves money right there.
Second- you would only pay 10% of your income. No loopholes, child credits, exemptions, or other hogwash. 10%. Everyone. You use the country's infrastructure, you pay. This includes the filthy rich.
Third- you only have to pay taxes for 50 years. From the age of 20 to 70, you pay taxes. Before and after you can make as much as you want without paying taxes on that income.
This is all for the federal government. The states would have sales tax of no more than 10%. Of course, groceries would be untaxed and every August school supplies would be untaxed, but other than that, 10%.
A government that can't run itself on this should be ashamed of itself.
