1. Na, some wealthy people would totally do that. It's their hard earned money and they're entitled to spend it however they want, after all. Get a job and stop looking for handouts!

2. Who says they even have excess wealth to begin with? I may make a billion dollars a year, but I'm living in this cramped mansion, and I've still got payments on my super-yacht. Living this lavish lifestyle is expensive!

It's because there's excess surplus from productivity gains. If you work 1 hour a day you can be far more productive than just a few years ago. Either wages should increase to match that gain or hours should decrease to match that gain. In both cases, wealth would be unlocked.
If you work fewer hours you get more time for hobbies and side projects and other wealth-creation ideas.
If you work the same amount of hours but for a higher salary, you get money to shift into investments or to be able to take time off to invest in yourself and your family.
The current surplus wealth goes to the top and to the company itself.
