Long story short, you can buy out diploma of any university( including the best "elite" ones) without even studying. You can still study on ur own and pay for most of the exams you have, moreover if you got "connections" on higher level you can just pay for all the exams coming in 4-5 years, no matter its Moscow or Tomsk. Meanwhile real students from mostly poor / average families struggle through corrupted and rigged system, and education since the school proposes them "an easy way" if they got money.
im not even talking about corrupted courts where the ones accused of murdering or driving drunk can simply buy freedom, this is on DAILY BASIS, in some cases you can just pay police to stop investigation and no justice happens to rich / powerful ones in that case. My brother was arrested in Russia few years ago for driving drunk and breaking speed limits, he paid 500$ to get out. In Ukraine it might cost 300$ or 200$.
This has become a way of life, i don't even think it can be cured, in Ukraine they tried to do it in "modern way" but failed, in Russia is just a way of life since 1991.
