Anyone know the process in detail? How did the state decide who got what job, and at what points were people forced into a particular profession? I imagine this must have started early in some fields (medicine, engineering, etc.) given the training required, but how did the countless other professions get properly allocated?

I'm assuming it must have contained some market mechanisms, like higher wages as incentives, but what other role did the state play in the allocation process?

And, finally, how do you imagine it would be different/more efficient in a "socialist" society?
