The US government has legalized bribery in the form of Political Action Committees, aka “PACs”. Each PAC is a special interest group that contributes to a politician in order to help get them elected. The PAC then expects an ROI - return on investment - for the money they contributed to the campaign. The ROI usually comes in the form of shilling for said special interest.

To add fuel to the fire, when Citizens United was overturned in 2010, it allowed dark money to be invested into campaigns. This shit was so significant, that I can actually remember where I was when I heard about it and can still feel the echos of dread. brennancenter.org/…/citizens-united-explained

This country is fucked. No politician will ever vote to repeal that. Why would they? The amount of money they receive from it would make Scrooge McDuck blush.
