We need to get money out of politics
A) America is a capitalist system. B) In America, the law is for sale.
Capitalism is a system that doesn't prevent the sale of law. Nothing in capitalist theory prevented the sale of law from happening. It literally was put up for sale and is now available to those with capital (aka, not you or me). Capitalism is the system of America. Capitalism allows the sale of law. Capitalism supports the sale of law, and the only thing stopping it is supposed to be democracy, but that's failing at the moment.
All of this to say, money in politics is a observably feature of capitalism, not a bug. This is a failure of democracy that's supposed to reign in capitalism but when so-called democratic leaders choose to not act, capitalism wins. This is not a surprise at all, because capitalism wants everything to be purchasable, even power and authority.
