Our politicians routinely sell out smaller issues for "downpayment in a coastal metro" level of money. It's just about within reach of a middle-class urban adult to directly fund with some personal sacrifices.
I feel like we like to imagine that these corporations are budgeting big-bucks to bribe/lobby politicians, because they have more money than most humans can actually mentally picture, but their budgets are often closer to a small team of software engineers' salary. Meta spend ~$25M on all lobbying last year - and they're the top corporate spender. That's under 1 hours of revenue for them.
