Americans will never agree to a national sales tax of any form, no matter the logic of it which the author spells out quite well. Politically it is impossible. Trump appears to be frustrated after 100 days of getting little done and is simply saying to his people, implement what I promised. Rip up NAFTA. Implement massive tax cuts with no offsetting revenue increases or spending decreases. Next up is an even farther right version of killing Obamacare, massive increases in defence spending (like 6.2% of GDP is not enough?). Etc... We will now see full bore implementation of his "agenda". I do believe this is extremely unwise, but it is not my country. We will see how it turns out and if Congress goes along. It does make me happy I was born Canadian though.
