At the high end, for skilled workers, there's a lot of people arguing what you argue, even the skilled workers who would face increased competition for jobs. And I admit, I find the argument compelling myself.

The interesting bit is that there are few who make this argument at the low end. The idea of open borders for unskilled folks is way less popular.

The net effect of this, it seems to me, is that while there's lots of support for me facing more competition, there's no support for more competition in the labor I buy.

Now, one could say that is reasonable, just because I make a lot more money than I need to live, which can't be said for less skilled workers, but it's an interesting dynamic.
