From Fed Chairman Ben Bernanke, speaking to the Senate Budget Committee recently:

“Increased rates of immigration could raise growth by raising the growth rate of the labor force. However, economists who have looked at the issue have found that even a doubling in the rate of immigration to the United States, from about 1 million to 2 million immigrants per year, would not significantly reduce the federal government’s fiscal imbalance.”

I hope this means we’ll never again have to hear an administration official or congressman justify mass immigration as a way to mitigate the ballooning costs of Social Security and Medicare.
