> First, political commentary should be regulated
Who does the regulating? The current Trump regime? Huge first amendment violation
> come from SA/Zimbabwe and comment on posts of US political candidates.
Because those posts are being made on a private platform. Are you sure you want something worse than UK's Ofcom proving your American identity just to speak?
> It should be compulsory for voters to vote
Maybe, but definitely not in a 2 party system.
> make them understand how the economy, the Fed, world trade, US intelligence, foreign policy, interest rates, and bonds work
Not specifically those. Please just have universal free education. There's no need to specifically teach kids how to think politically. That's definitely going to get abused for propaganda
