Re: They invest the money which brings jobs
I'm back on a keyboard, so now I can respond in detail.
"This comes back to my question of where? Do they put it in some vault where it is locked away never to see the light?"
Depends. Most invest it in idle stuff like real estate that, by simple dint of human growth, becomes increasingly scarce and thus more valuable. That's why it's the go-to investment for the REALLY rich. Thing is, once they lock in their investment, THEN they sit on it. After all, why bother to move it if you don't have to. It becomes a nest egg. Plus it helps in Tax Planning 101 (aka Buy, Borrow, Die), where they borrow against their assets to avoid taxes (heirs then use the carry-over basis to pay the debts off after they die at reduced capital gains taxes).
To take a literary example, consider the late Terry Pratchett's view of the rich through the perspective of the Ramkin family: old and very, very rich because they're holding lots of value that kept appreciating over time.
"This is an option most people have yet still the number of people I know who spend it all and more amazes me. So many people could be so much more comfortable if they didnt just spend all they had and more, but their interest payments do provide cheap and free bank accounts for the rest of us."
Thing is, the Cost of Living tends to be inflexible for a given area. More people than you know aren't earning enough take-home to cover this; many others are barely over and still need to cover other necessary (and sometimes unexpected) expenses. It's hard to save up when your paycheck is already spoken for.
This is true. And people from those societies seek to reach our societies. However some people in our societies seem to desire changes to turn into the more dangerous societies.
