It's because politicians are bought and paid for by the very companies we're talking about. The only way to bring about change is to vote out the incumbent every time for 20 years I'm afraid. That's about the only pressure that will actually work. They are voting the way they do for self preservation via campaign contributions. The only way we can counter that is threaten their self preservation by voting them out every time. Between Andrew Jackson to U.S. Grant, there were no 2 term presidents. Maybe they knew something we didn't.
