There is a huge displeasure across native dwellers of Russian cities for the behavior of Southern migrants, especially from Chechnya.
Now, the simple fact is that under the old Soviet regime—or even most of the Czarist era- there wasn't a lot of illegal immigration. This displeasure is not just with the immigrants themselves-but with the economic elite that as emerged since the fall of the Soviet Union. Now, the last time there was "huge displeasure" in Russia around the behavior of their economic elites, we saw events set in place that eventually resulted in over 60 Million people getting killed. I hope this history isn't lost on those making decisions in Russia.
