who control everything both here and abroad.
We can solve all the issues you have mentioned. Workers could have shorter work weeks and more leisure time. Population can be controlled - I see no reason for families to have 20 kids .. there could be incentives to keep families smaller. Climate change is very serious, but we could take steps to do no further damage and start remediation efforts. However, we will not do that as long as capitalism is the economic system.
It was an interesting sociological experiment in this country from the end of WWI to roughly 1980 (so about 50 years) in which there was an attempt to reapportion wealth to level the playing field a bit (much higher taxes on the top levels for example) - and it couldn't last because that was not enough for the capitalists. When greed is the motivator it takes over. So regulations were cut, jobs were outsourced, unions were broken ... and now here we are with the Walton family controlling more wealth than 40% of the rest of the country. Just think about how crazy that is ...
We've seen what happens when private enterprise competes with government entities. Take the post office for example - they are being deliberately run out of business. Soon Pitney Bowes will take over and that will be more decent jobs lost - replaced with low cost employees and likely robots down the road.
It probably is pie in the sky to think that this can be done peacefully, sure, but I think eventually people will have so little to lose that they won't care (and that's when revolutions occur).
