The idea that concentrated wealth is great for everyone and will trickle down has been pretty much debunked to the point where the wealthy are openly stating we don't need the masses anymore.
The crypto dystopian nightmare of generating money with zero utility backed by quantitative easing demonstrates that you don't actually need many employees to generate wealth. You don't even need commerce, financial engineering will suffice.
Employment is a social contract. Business owners and investors (who control capital) are supposed to provide a means for the masses to live in comfort, the employees give there labor and time in return. The wealthy get to live in their mansions, vacation on their yachts, etc. We get to buy our homes in the suburbs, raise our families, etc.
What happens when no one works and humans are removed from the value chain?
