Capitalism's "race to the bottom" has made us rich beyond the wildest imagination of the people of the past. Our children do not have to work. Most jobs are indoors, in climate-controlled buildings. The rich may drive nice cars, but many of the poor have cars too. In the past, the rich rode in carriages and the poor trudged through the muck with no shoes.
Automation is what allowed us to go from the vast majority of Americans working in the fields to agricultural employment being 2% of the labor force -- and we produce more food than ever.
