I think this is it, actually. Having a lot of money can lead to spending it on frivolous things, but I don’t think that’s what we mean by corruption. It’s when you have so much money that you can use that money to influence people in power that it gets bad. Suddenly, when getting your way is merely a question of bribery and you have plenty of means to do it, people start thinking they have a right to pull the strings in the way they see fit.
