He's not correct on all accounts, he just sounds like a politician on all accounts. What will making college tuition free do to make America a booming nation again? How does he know what tuition will cost from year to year? The increase in tuition at colleges and universities increases by 7-13% each year since I was in school. Inflation has run from 2-3.5% annually for the past decade. How fast does he expect his new tax will grow? The number of transactions on the exchanges aren't grown 7-13% earch year.
Besides that, sending kids to school to have them all study poetry or underwater basket weaving isn't going to do us any good. We need to refocus our kids towards STEM courses, find a way to get their interests flowing in a direction that will help aid our high tech economy. Psychology degree holders that end up asking if you want fries with that might be cliched, but it's not far off. Sure, it's more like they're asking what you want on your double-something machiatto, but it's the same net effect only now with more caffeine.
Free trade is not a mistake. Free trade has likely kept us out of wars. Who doubts that an aggressive China has been tempered by its business class the same way the US has been to some extent or another? Without free trade, without those business interests in foreign lands, we have no idea how far Bush would've pushed our nation in search of war. Given the sabre rattling coming from China in the Yellow Sea/Sea of China, without concerns from both nations' business classes and the normalization of trade relations between us and them, I'm confident we'd have seen at least some degree of bloodshed by now. If we think Mexico has its problems with drug running and growing now, without American businesses relocating there, they'd likely be all the more overrun with poverty, increasing the temptations of their youth to join the gangs that have ravaged their lands, already sending their poor sneaking across the border to the US. Whether you like it or not, NAFTA is probably saving lives.
