The problem really isn't with the immigration act of 1965. The problem is with the welfare state. When poor immigrants came at the turn of the 20th century, there was no welfare state so they had to work. Working to provide for oneself has a strong tendency to make one conservative. When new poor immigrants come, they are presented a welfare state that promises to give them everything. They no longer have to work and still live better than where they came from. This has the tendency to make one liberal. We have crossed the tipping point. Had Romney won, perhaps we could have addressed the welfare state. I don't think it is possible anymore as the takers apparently outnumber the makers.
