naaa... not really. they forget really quickly where they come from. Money corrupts everyone, no difference if you have a few million or a few billion.
A few million means you own your house outright and could retire right now. It's success for yourself but it's not political control the way a few billion is. You couldn't afford a big misleading media campaign to change a law. It's not even generational - your kids will have a good upbringing but won't be set for life (other than housing maybe)
