I’m pretty sure that future billionaire me seems like a cool guy, I’m totally not biased.

Eat the rich, except if I become rich, then I’m exempt because I am a honorary proletariat

/s but seriously tho, if anyone becomes a billionaire, they’ll soon get corrupted by the wealth

You don’t become a billionaire without exploiting so many people and then hording those riches to yourself. You’ve already been corrupted by that point.
A horde would come after their hoard of riches
