That's because most people don't have the ambition and discipline of Elon Musk or Jeff Bezos and if given the chance would rather bum around their whole life instead of work.
I see the same thing in Austria and so do my friends living in other wealthy European countries with strong social nets.
Most people, if given easy access to welfare, would rather lower their standard of living to fit in that small sum of money and not do anything all day rather than use their free time to hustle, learn a new skill or build a business that will permit them a higher standard of living later on.
