"And there are a lot of self-styled "conservatives" who don't love American families." Perhaps, but I don't know any.
There are a lot of people who claim that totally free trade and unlimited immigration is good for America, and they do this on the basis of conservative economics. Some of these people happen to be conservative on issues like gun control and abortion, as well. The charge that they don't really care about American life is very sticky.
I don't think they really love American families. I believe in fair competition, but not with slave labor, government-subsidized factories, and workers trained in free universities and desperate for the chance to work at any rate.
We can compete if we take care of our own people. If we fail that, we'll compete with no one soon.
