LOL, ok there's a few factors at play here.
1: most Americans don't even understand what the economy IS. when you ask them about the economy, they're going to answer w/r/t their personal finances. which, for most Americans, suck.
2: stop looking at the stock market. the stock market has zero to do with how people are faring economically. most Americans don't even own stock.
because Republicans don't argue in good faith. they aren't honest about anything. Republicans are spamming social media with shit like "WE WERE BETTER OFF UNDER TRUMP" purely because the guy they liked was in charge. purely because he pissed off people they don't like. they would gladly be rounded up and executed by Trump and they would claim they're better off for it purely because it would upset people they don't like.
what, to keep Americans in? because nobody's going to make it all the way to Canada just to turn around and try to sneak into this hellhole.
Canada and Mexico both have strict gun laws. the guns used by criminals in those countries are coming FROM THE US. if we passed strict gun laws as well, we cut off the entire supply. and that's how we achieve a result like Australia's.
