This YouTube video (http://www.youtube.com/watch?v=n7WJeqxuOfQ ) which has been viewed by 3.1 million people, features Roy Beck, executive director of Numbers USA, graphically illustrating what the Census Bureau says will happen by the middle of the next century if the U.S. refuses to change its current immigration policy.

The U.S. population has doubled since 1970, largely as a result of letting in one million foreigners annually. If immigration continues at today’s rate, Beck says, our population will quadruple and every community in America will have to grapple with the same problems now facing California, where “an entire elementary school has to be built every day in perpetuity to keep up with demand.”
