Immigration into the US was curtailed in the 1920s and then reopened in 1965. This period was one of relative wealth for the middle class. Since the late 60s to early 70s, the middle class has suffered an ever-decreasing quality of life. It doesn't seem like a foregone conclusion that reducing immigration will necessarily lead to a decrease in quality of life. Increase in the cost of some items (the ones whose price hinges on cheap immigrant labor) would be met by increase in wages, especially for people in the lower socio-economic rungs.
