Hmm this is an interesting article. I always wondered what if it wasn't the Hispanics that proved to be a majority in this nation by 2050 but other Europeans. Of course this article doesn't talk about this, it does attempt to dismantle the idea of how whites will be a minority by 2050:
“Whites will become a minority of the American population by midcentury if not sooner,” states America Enterprise Institute scholar Charles Murray in his fascinating new book, Coming Apart: The State of White America 1960-2010. In repeating this claim, Murray (likely unintentionally) furthers a misconception about the country's shifting racial makeup and what it means for the future of the United States.Here is one thing from this article I can agree with, "America is an ideal, not a tribe." Yeah hopefully no one can disagree with that ideal. No one group racially or ethnically can claim themselves to be American. People came to American for a dream of some sort. We worry about ethnicity and then lose what makes America great!
Murray's likely source is the much-ballyhooed 2009 U.S. Census report [PDF] that parsed certain immigration trends and fertility trends to reach that conclusion. But the claim that “whites” will be a minority in America by 2050 implies an invidious view of the importance of ethnicity and race. “Whites,” by earlier definitions cherished by nativists, are already a minority in this country and have been for many decades. The successful amalgamation of previously scorned "races" is a testament to the ever-broadening inclusive tolerance of the American social project.
