I can tell you stories of third-world immigrants who had a happy marriage in the third-world, but within a few years of moving to America, their wives mutate and turn on their husbands like rabid dogs.
It is the same with the children of immigrants: Those families come here looking to make money and live high on the hog, but in the process their children grow to run wild, which is a dreadful price to pay for financial prosperity.
Of course they thought THEIR children would behave the same as they did in the old country.
And so men think foreign women will behave the same.
But women fall prey to similar influences.
I could tell you many of the same type stories --- it almost seems worse for those who move here from 3rd world countries. The wife starts arguing back, the kids start thinking they don't have to obey.
I know some immigrant couple who had a very hard time with their daughters, especially the mother --- the daughters wanted to listen to rock music --- and they said back home, kids just listened to what their parents listened to -- the parent's missed the whole 70's music thing in the USA -- which would have been their decade of growing up -- so they took it as some kind of rebellion --- then the daughters did things with their hair --- slightly punk --- American parents wouldn't think anything of that --- but it was difficult for this family who thought the kids were just trying to hurt them.
