look, US politics is a shitshow, regulators are beholden to politics, lobbying is a very big influence in the US. from the crazy anti-porn, anti-abortion, anti-gay/trans, anti-welfare xenophobic fundamentalist anti-anything lobby to the anti-gun, super-duper-pro-trans, militantly-feminist, pro-eat-the-rich lobby.
and during all this banking in the US suffers from all the usual problems, it's 50+ regulatory regimes all in one, banking systems are laughably ambivalent old and legacy plus too new and full of bugs, and so on.
it's not surprising that things are not ideal. there's no need for some extreme conspiracy. big banks are user-hostile. just as the police, as healthcare, and so on.
