Because Putin still didn't purge all oligarchs that were plundering it and transferring money to the West
You mean the great geo-strategist genius who doubled the length of Russia's border with NATO hasn't been able to fix Russia in 23 years? Shocking.
Number of billionaires in Russia when Putin started his promising career of a genocidal dictator: 0
Number of billionaires in Russia today: 100+ (due to sanctions might be down to ~80 by some estimates)
First of all I couldn't find a better name for the "disease" killing oligarchs like flies. It is the so called:
The number is shrinking rapidly. I am too lazy to list the countless sources here stating ridiculous stories of how all those people coincidentally fall out of windows, have a stroke, fall off the third floor in a hotel, kill their entire families and then themselves, etc.
But all of these cases have one thing in common besides being statistically unrealistic (if not impossible), as we are talking about a tiny, tiny, tiny subset of society experiencing excess mortality such that the odds to win the lottery is countless times higher. They have in common that they criticized Putin. Putin denies that he has anything to do with it, of course he does. That's the point of his strategy.
To the Putin fans here, what would you say if 38 of the most important people (sometimes including their families) die in the USA after they criticized Joe Biden? When the Crimea was annexed, 38 died between 2014 and 2017.
Now, at least from what is publicly known,
another 32 have died, some are in prison and are probably
going to die as well like Igor Shkuroko just 3 days ago. There is only one cure to the "Sudden Russian Death Syndrome": don't criticize the psychopath Putin and do whatever he wants even without him asking you. If you don't you get a mysterious disease or you "commit suicide" because you started hating your boring oligarch life.
The coincidences are so ridiculous and Putin is killing all over the planet. It is disgusting to read that he is even willing wives and daughters and sons at child age.
To the Putin trolls: where is the line for you guys that you would say "ok, can't be coincidence, and it is ugly what the psychopath is doing"? Would you even do that in case you realize it must be true? (no worries, you wouldn't realize)
