Capitalism have had a couple of hundreds of years or so now, and it still haven't succeeded in this, even with all the technological progress since.
I'd argue it's not. I'd argue prosperity is. That is to say if the poor get far richer than they were and that keeps happening I don't care if the rich get richer faster. Especially if true class mobility is present in the system. That way the poor are trading places with the rich.
The problem is that it's becoming increasingly clear that Capitalism fails miserably at redistributing resources fairly.
Yes pure capitalism fails some people and a mix of small amounts of socialism help those in need. But prosperity does far more to help the poor than equality. Extreme inequality is bad
I'm saying that absolute wealth is more important than equality. Do you have a counter to that or a system that can promote prosperity and more even wealth distribution?
