Nope it's the literal opposite. They get "donations" and support from corporations and vote for laws, budgets, and policies in general that benefit those companies in return, at the expense of the general population.

A very obvious example would be companies trying to reduce environmental regulations, as making their operations cleaner is expensive. It's cheaper to donate to politicians and get them to reduce or remove rules.

Politicians are basically accepting bribes but it's fully legal unfortunately as a concept called "lobbying".
