> Nobody needs an economic incentive to work (please prove me otherwise).

"Nobody does X" is too strong a statement; when you say something like that, the burden is on you to prove it (by asking everyone in the world, for example). I personally know quite a few people who wouldn't work if they didn't need to.

It's true that some people don't need an economic incentive to work, but others do.
