Back in the 90s I was taking Russian language classes and was looking for a Russian pen pal online. The amount of women looking for a husband to come over was ridiculous. Their economy was crap and marrying out was a good investment.
There is also the demographic collapse of Russian men. Due to alcoholism and like their life expectancy is on par with Third World cesspits. The demographic mismatch that occurs between men and women, due to men dying earlier, is accelerated in Russia.
