Yeah I don't think there is much hope there so long as corporations are donors to political campaigns (Something that still looks weird when I type it, but presumably doesn't sound strange to a US person).
Sadly, it’s not exclusive to the US. In Brussels we might jokingly dismiss the lobbyists and their think tanks, but they fund politicians just the same; but admittedly via non-profits and other more intricate schemes. I’m very proud of some EU accomplishments, but we’re mired in lobbying too.
