Suppose you win 100 million. What do you actually do with it? Banks only guarantee 250,000. Do you have to invest it? Is there anywhere you can just let it sit and draw interest?
Finally get rid of the biggest barrier to a better world for at least 300million people, primary/buy-out every single politician of the democrat party to ensure the things that are ostensibly in their platform are actually enacted. Also ensure that every single current non-elected neo-liberal "policy wonk" and their sycophants never have any influence in any future government again.
I don't think 100 million will buy you a hill of beans in US politics. And I don't think they'll betray their class interests for any amount of money - what's the point in taking a $100m bribe if it means there's fair taxation and more equitable living that prevents them being top dog with that money?
