America has a monopoly problem
America has a corruption problem. The ability for companies to vertically integrate and essentially make smaller businesses non-competitive can only occur when you don't have to pay the taxes your smaller competitors have to pay and don't have to obey the same laws your competitors have to obey.We have a systemic corruption problem (manifested in lobbying) coupled with greed on scales we've never seen before. Everything else is just a symptom of that problem.
