Applies to work life too: if you just work more then you can become rich. But what happens when everybody works more? You get the same basic stuff, but now you really have to work for it.

Shouldn't there be more stuff for everyone then? Something is wrong if there weren't.

Only slightly. The question is if this small increase in stuff is worth the total degradation of ones life quality. I say it doesn't. You earn more but then you spend that extra income on expensive stuff that you don't need just to feel that you are still living a good life.

Oh oh, sounds like you're arguments are about marginal utility, subjective value and economics trade off. Are you a crypto austrian ;) ?

I don't know what crypto austrian means :) I'm romanian.

Crypto-* to say that you are that * without knowing it.

Austrian refers to austrian economics ( https://en.wikipedia.org/wiki/Austrian_School ), you basically said in one sentence the 3 economic concepts I said earlier.

Spoiler : nobody ever justified communism / marxism / socialism based on this.

I guess I might be. Thanks for the link. I didn't know about it.

So what happens if nobody works ?

Communism :) I guess the ideea is to work but without forgetting the other important parts of life.

   the other important parts of life

Like eating food ? You need people to work for that

More like family, rest, active rest, friends, painting and so on. All the activities that have no imediate economic value.
