Speaking of immigration:

A flexible labour market and stingy welfare state ensure that there is no resentful immigrant underclass with time on its hands, as in France. By the standards of most other advanced countries, America is hardly crowded. It has a proven capacity to absorb large numbers of migrants. And its swelling population—the Census Bureau thinks there could be 500m Americans by 2050—means that the next superpower may well be not China, but the United States. Now there's an idea conservatives can applaud.
