Lol. Who else is in this class? Little Piotr Communism dropped out of school 30 years ago. China's busy just trying to catch up. Everybody else can't seem to figure out how to pass econ-101.
Oh please. The answer was globalization. People couldn't get along well enough to make that work so here we are.
There is no magic sauce that will make economies work for everyone. Specialization is how we built civilization tens of thousands of years ago. It's how we get off the struggle bus today. But if nations can't rely on a global trade order then they all have to build everything.
