What do you propose to fix this system?
If a reader believes that the current system is the best system possible, than these politically-charged complaints sound as futile as politically-charged complaints about being unable to exceed the speed of light.
Managerial positions are of course kept (as managers are wage labourers too), the only difference is that there isn't someone at the top to collect surplus labour.
This is otherwise known as anarcho-Communism, or some variant of social anarchism. I am reading into communalism too (Bookchin) and the question of how those in service jobs can own their labour is an interesting one, I'm not aware of the current research on that.
