Contrary to the claims in today’s piece by William Kucewicz, immigration is, according to the Census Bureau itself, a “highly inefficient” method of reducing the ratio of dependents to workers. As my research director pointed out last year, immigration over the past generation has had virtually no effect on our society’s age structure mainly because, as Kucewicz himself suggests, it would have to be increased — massively — to have a notable impact. And the Social Security Administration’s own estimates show only a tiny benefit to the program from immigration — which is almost certainly exaggerated because SSA assumes that immigrants have the same earnings and tax payments as natives from the moment they arrive, which is absurdly false. In short, our Social Security problem can only be fixed with Social Security reform, not dodged by implementing harmful new immigration programs.
