True. And there is also a huge influx of Russian war widows advertising themselves on mail-order-bride websites, flinging themselves at lonely middle-class Western men who either can't win a woman over and thus choose to buy one instead, or who actually WOULD make decent husbands but haven't found a woman in the West worth the effort (either one is the same to a Russubus, as long as he's single and can sponsor a visa and support her vanity). This, in turn, exacerbates the number of embittered single women in the West who blame "The Patriarchy" for the fact that men are not beating down their door and fighting over 300 pound misandrists.
Strangely enough, I see Ukraine being a more likely place for polygyny to become accepted. It's old-fashioned enough that it's still Patriarchal, but liberalized enough that "Traditional" (read 'Catholic') definitions of marriage aren't so unshakeable anymore, in contrast with Russia where the Orc-thodox Church (with their former KGB Pontiff who preaches occultist Shaman Aleksandr Dugin right from the pulpit) holds the same sway over the State that the Catholics did over the Holy Roman Empire.
