I'll wager that the guys aren't always pigs.It's just like divorce here in this country.It's now SOP for a woman in a divorce case to claim spousal and/or child abuse. Even if it's not true,she has an important leg up in the case.
Same with Russian women.They come here,they claim abuse, they get an immediate green card (under current Federal law) and before you know it,she's got a green card,a welfare check and she's hooked up with a guy named Vladimir from Brighton Beach.
Many times Russians and other gals find a way to get rid of the marriage and husband. Threat by Russian thugs can do the trick. My friend was offered $25,000 to marry a Chinese woman. He turned it down because he felt he would somehow become enmeshed with the Chinese gangs here. All they have to do is demand the return of the $25,000 after the marriage takes place or you get mutilated. Who wants to have to look over his shoulder? Same for the Russians. Marry the wrong girl and you are toast if you don't accommodate the thugs that come with her
