I think you might be missing their point. I'm already paid (less than) 20 % of the value of my output, because someone who is already very rich pockets the rest

I think you might be missing their point. I'm already paid (less than) 20 % of the value of my output, because someone who is already very rich pockets the rest. If I could continue working as much as I do and get paid the same and also know that the other 80 % of my output feeds the homeless and seriously ill, that would be amazing. I would very likely work even harder.
