>1. People lost ownership of the things they work on. In the early 1900s, more than half of the workforce was self-employed. Today, it is 10% in the US, 13% in the EU.

At a high level nobody works smarter and harder than people working for themselves because they see the direct results in near linear proportion. So basically half the workforce was in that situation vs a tenth. Say nothing about taxation and other things that cost more the higher up you go and serve to fractionally break or dilute the "work harder, make more, live better" feedback loop.
