> Things people used to take for granted.

All of that was possible mostly due to a confluence of a few major things that happened at the right time - WW2 leaving US at a competitive advantage, people having lots of kids ensuring lots of economic growth, and automation and outsourcing multiplying productivity and keeping costs low, but at a slow enough pace that people could transition to better economic opportunities and a lot of the people being left behind were masked by sheer population growth since a lot of younger people were still moving up on the ladder.

And no automation was developed to turn people over in the hospital beds or change their bedpans or clean bathrooms.
