How come we use currency, what if everything was free and done by charity workers?
What do you mean "everything done by charity workers"? You mean the jobs that we have now?
So your vision is that a huge portion of the population got shit for free (which they'd probably have NO ownership over due to it being completely free), and then some small bunch of people would be those who worked their asses off and got nothing for it?
Or one where
everyone has to work to get shit for free, so they could lead a normal life, and not die on the streets?
"But what if those who don't work jobs also get free shit?" Well, that's the point, then there'd be a buttload of freeloaders. If everyone got free shit, there'd be freeloaders. If those who worked for society got free shit, there'd be a lot of homeless people.
And, above all, people like to have more shit than others. It gives them incentive to thrive, and to go forward. If no one got rich, and everything was free, no one would probably put as much effort into doing things that usually net people lots of money (new, revolutionary ideas, products, services etc.).
