There's really only so much money a person even needs anyways

What the heck would I do with billions?

The answer for these guys is "hire armies of financial advisors to make even more"

The answer for me would be closer to "hire a financial advisor to work out how much I likely need for the rest of my life, double it just in case, then give the rest away"

You can argue that I wouldn't actually be that way if I got that much money, and you might be right. You can also argue that maybe people like me don't have a hope of getting that money precisely because of my mentality and you might be right about that too.

Either way it seems to point to something deeply broken in these people, imo.
