it does need to make sense or it does not hold water.
would you move your wife and kids away from the home you all love to go half way around the world to a place where they hate you just to get welfare? of course you wouldnt, so why would they?
I am just saying what they are doing. Their mentality is more about them, less about their wives or children. For example, father will get the safety vest on the sea, neither his children nor his wife, if there is only one vest. It depends. I cannot give you response for all millions of immigrants what are all their motivations. I gave you just the main, most common ones.
