Work is indeed the main problem. It doesn't need to go away entirely — in fact I think some amount of work is on the whole beneficial, but the status quo is clearly not sustainable. It's not reasonable to expect people to burn away the overwhelming majority of their lives just staying afloat and not become depressed and burnt out somewhere along the line.

Work is the whole problem and the fundamental driving force of civilization. It’s the transference of the pork to other so some don’t have to do any of it. That’s civilization in a nutshell.

Not forcing people to work would have us reverting to an animalistic state in a generation though.
