Do you really think that's sustainable?

Four million Americans turn 18 each year and begin looking for good jobs in the free market.

But the federal government inflates the supply of new labor by annually accepting roughly 1.1 million new legal immigrants, by providing work-permits to roughly 3 million resident foreigners, and by doing little to block the employment of roughly 8 million illegal immigrants.

It actually is sustainable for third-world immigrants. Certainly not for Americans looking for a living wage.
