mkUSAgreatAgain: My letter to the president

Dear President Elect,

I expect that you'll get a large number of requests for help, many of which will be to help others and not the author. That is one of the great things about persons, it isn't just about themselves, instead life should be better for all. But the United States of America was great, not for what it did, but instead for what it could not do. I want to make my suggest toward fixing the government.
