I still don't get why you think making money is pointless if you can't spend it on healthcare. There's plenty of things you either use while paying for them in taxes (e.g. roads) or things you wouldn't be able to buy even if you wanted them (a private spacecraft, too expensive, or a child prostitute, too illegal) yet they haven't made you stop wanting to earn money.

I'm covered by the NHS, I still find plenty of reasons to cash my paycheques.
