Chinese here.
Did you know that China is run by assholes with an engineering degree?
Seriously, Chinese officials tend to buy a degree to make themselves look more educated.
(me injun)
It was hard in USSR to buy degrees and many USSR leaders actually have degrees. But our former leaders successfully exploited various loopholes in the education process and got good grades for social/political activities, not for education achievements.
So all in all, those looking for power will find their way through any system.
