You are focused on the “labor” compoenent….while ignoring the “consumer” component, which is 1000X bigger.
You need to go listen to Milton Friedman on “the pencil.”
The labor component is important if you decimate the jobs of the middle class who are the biggest consumers. Depressing wages will not help consumers in this country. And when you eliminate jobs, you put more people on the dole. The welfare state is quite advanced in the US. Replacing low skilled Americans with low skilled immigrants who work for lower wages does not help the country. We are getting ready to do the same thing with skilled labor.
It used to be that we needed more immigrants to do work Americans won't do. Now we also need them to do jobs Americans can't do. We have 90 million Americans of working age (16-64) who are not in the work force.

I have seen and heard it many times. FYI: Milton Friedman said, ""You cannot simultaneously have free immigration and a welfare state."
