1.) Don't impose tariffs. I know being a protectionist is part of Trump's appeal but more jobs will be lost than created. Also, if you raise the price of imported goods the cost will get passed on to all Americans and hurt lower-income Americans even more. It's a weird obsession of his and his only consistent principle since the 80's. You know it's a bad idea when Bernie Sanders pushes for the same thing.
2.) Pass a federal flat tax of 12% and largely reduce the IRS. Nobody likes paying taxes (rich or poor) and it would lead to an economic boon. Lower the corporate tax to 16%.
3.) Convince Thomas and Alto to retire while you control the presidency and the Senate. Replace them with younger conservative judges. Obama couldn't convince RGB to retire and it ended up biting them in the back.
Bonus: Make Daylight Savings time permanent. I'm sick of it getting dark so early this time of year.
