The Economist heralds immigration:
Immigration keeps America young, strong and growing. “The populations of Europe, Russia and Japan are declining, and those of China and India are levelling off. The United States alone among great powers will be increasing its share of world population over time,” predicts Michael Lind of the New America Foundation, a think-tank. By 2050, there could be 500m Americans; by 2100, a billion. That means America could remain the pre-eminent nation for longer than many people expect. “Relying on the import of money, workers, and brains,” writes Mr Lind, America is “a Ponzi scheme that works.”
Another paragraph worth pondering:
It is possible that unskilled immigrants hurt the wages of unskilled locals. George Borjas, a Harvard economist, estimates that native workers’ wages decline by 3% or 4% for every 10% increase in immigrants with similar skills. But others, such as David Card of the University of California, Berkeley, have found little or no impact. Gianmarco Ottaviano of the University of Bologna and Giovanni Peri of the University of California, Davis, find that nearly 90% of native-born American workers actually enjoy higher wages because of immigration. Many immigrants bring new skills and ideas, spend money, pay taxes and employ natives.
