Some people are leaving Russia, some of them are decent and some certainly have their good reasons to leave. Anyway, it is compensated by influx of immigrants by large margin.
If Russia was really such a bad place it couldn’t be such a massive magnet for immigrants, second only to the United States in this world.
Just check stats from respective international bodies. US is a #1 place to go, Russia #2, Germany is a (distant)#3. All the rest countries combined aren’t attracting as many foreigners as these three.
Russia is getting a huge influx of muzzies from Central Asia. Moscow streets like those in Paris are now blocked by massed muzzies kneeling at prayer & they demand worship space in Orthodox churches.
I was deployed to Uzbekistan ten years ago. Even then young Uzbeks told me Russia was their window to the West & that nearly a third of the population was in Russia either working or seeking work.
Uzbeks are Muslim but not the worst, tending to be secular, far more so than Afghans whom most Uzbeks despise for their harsh Islam.
Siberia is filling with Chinese but that’s another story.
