Why did the separation of ownership from control happen? Primarily due to the widespread use of birth control among whites. Franchised women consistently vote for the big government, for regulation and for the safety net. Big government actually disfavors small and hereditary businesses, since they are harder to control than a few concentrated anonymous conglomerates without real owners. Plus there are fewer capable sons in a nuclear family to pass a business on than a 100 years ago (also think about single moms here).
Reduced white fertility also led to replacement of the bulk of white work force with a lower IQ non-asian minorities (NAM) workforce. In the age of hi tech and automation, such work force is largely useless. They are kept occupied however, to reduce crime rates (think of Detroit riots of the 60s).
Additionally, the overall effect of women in the workforce is also counterproductive- more workplace drama than actual creative work.
