Since the current system is deeply unfair, I'm not sure why adding additional wealth to the system would make it any more fair. The majority of every extra dollar goes to the ultra rich.
That's just an opinion. What we do know is that as more wealth has been generated via Capitalism more and more people globally (and nationally) have been brought out of poverty to the point where poverty has had to be redefined in certain areas. Capitalism has made starvation a thing of the past and diabetes the new, but better, problem of the poor for example. Poor people can afford to eat meat daily. Not even wealthy could do this in the not so distant past.
So instead of fighting over probably wrong opinions we should look at the data and then continue to do more of the thing that has been generating better outcomes for more people. That means more capitalism because that leads to better outcomes.
Removing it brings about the outright terror seen every time it gets removed. Change my mind.
