AB stated: " ...my reading of the relevant Productivity Commission report doesn’t match that assessment. Despite it taking a very narrow and short-term measure of what constitutes economic and social benefits, it still found a small net gain from migration."

Those "benefits" amounted to a 0.06 percent increase in per capita income. In other words, chicken feed. And when balanced against some of the substantial costs of immigration, such as downward pressure on wages, higher housing costs, increased consumption of natural resources, higher water costs, a larger current account deficit, and increasing welfare and tax burdens on state and local governments, those "benefits" disappear completely.

Immigration is simply a way of driving down wages and boosting demand for goods and services. It benefits the big end of town and those ethnocentric minorities seeking the importation of more of their own, but nobody else.
