Are those three not in the same "class"?

While Gates was richer than Jobs, once you're in the $100B vs. $10B, you're mostly in the keeping score category. Woz is apparently worth about $100M which is still in the you can buy pretty much anything you want category. So I would say yes.

On the other hand, someone who is worth, say, $10M or $20M is obviously still quite wealthy. But not necessarily in the doesn't need to think twice about hopping on a private plane or owning a private island category.

Not initially anyway its not all about money

So what is it about? You're acting like we should all know what you mean. Typically when someone talks about class they referring to income, wealth, and sometimes debt.
