It's more a measurement of how useful you appear to rich people. You can't make money being useful to people without money. You can make money convincing rich people you're useful to them when you're not.
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, but I don't think this accounts for all or most or much movement of money.
You may live in a bubble
