As recently as 1800, almost all Western men were self employed.
Even in the early 1900s, Henry Ford had to offer 4x to 5x the going rate for unskilled labour to get even desperate recent immigrants to take dead-end assembly-line jobs with no prospect of becoming one's own master.
Now, though, even most professional office work is assembly-line and "stove-piped".
This level intermediation, centralisation, dependency and parasitism didn't "just happen", it required construction of new ideological and cultural institutions, and a lot of violent intervention by the State.
