Asking this question leads me to suspect you have no true curiosity or willingness to learn a new perspective as it's literally a Google away. And then you will reply in another direction that justifies your narrow world view that is of course justified 100% by your experience. This is not effective discourse and I see you doing it all over.

It’s a well-documented economic concept. You can find plenty on it if you're actually curious about the perspective. And understanding it thoroughly is a strong prerequisite to seriously engaging with other people with intent to learn. It's work you need do yourself.
