I know we have citizens united but corporations are not people lol

Citizens United didn't make corporations people. Corporate personhood had been a thing for a very long time, largely about whether or not forming a business means you lose legal rights operating under it (Does a business entity have freedom of speech? What does freedom of the press even mean in an 18th century context if it doesn't apply to a business [aka a newspaper]?) and whether or not regular old laws prohibiting a person from doing a thing can be applied to businesses.
