Sorry, but there is a little bit of muddling.The communist ideology on the other hand postulates the planned economy... [...] Upon the graduation those students can only take the government's job and can only accept the rate established by the government. [...] Your education belongs to the state the same way anything else does. The education is free, but it's not yours. No muddling.
You make it sound as if these graduates were limited in their choices (state jobs ONLY), while in fact they could work anywhere (within their area of competence, of course), since technically ALL existing jobs were provided by the state (be that a janitor or a rocket scientist). And all these jobs were available to them.
