Yes, there will be some people who don't work but there will be others who do work and that will cancel out.

If only that were the case. There's way more people content to live in huts and open sewers than those addicted to work and improvement. Look at India for example.

literally working Uber but he stopped because he found the earnings wasn't wroth it for what he did when factoring in taxes.

First of all, so he didn't know he had to pay taxes on his Uber income? Or what the tax rate was? So basically he's a moron. You're basing your views on what a moron said. But good on him landing that $100k parasite job at whatever unfortunate company hired him.

You may be right, he might work Uber on top of his extra $30k from no taxes, but for a different reason: because basic needs and everything else would cost much more than now (this was my original contention, btw, that you're agreeing with).
