> It's more a measurement of how useful you appear to rich people. You can't make money being useful to people without money.

I disagree that the two types of people are "rich people" and "people with no money"; the latter of which is vanishingly rare in developed countries.

> You can make money convincing rich people you're useful to them when you're not.

You can, but I don't think this accounts for all or most or much movement of money.
