Pretty much all the problems in the US boil down to 3 things:
1. Too much money in politics
2. As a corrollary to #1, too much corporate power, including horrible regulatory capture, defanging of most regulatory agencies in the past few decades, and few institutions standing up for workers needs or general human needs
3. A really ****ty media / advertising culture that has turned everyone into zombie consumers with no empathy (a bit exaggerated maybe, but only a bit)
