Will the U.S. Become Majority Minority?

No.

Yes, I know that California and Texas have already become majority-minority, with Hispanics, African-Americans, Asian-Americans, and Native Americans outnumbering the rest, but I doubt it will happen to the U.S., ever. Why? Let me go back in history. [yes, oldtimer, and let us sleep]

In the 1950's the WASP (white anglo-saxon protestant) dominance of America was slipping. A Catholic would even become President in 1960). To some that was as big an issue then as majority-minority is now. But now? We are all WASP's now. The issue of which people running for President are Catholics, which have a non-anglo-saxon background, is a non-issue, raised only occasionally as a space filler. Yes, I may be overstating my point, but the tone of the society is WASP. For all the jeremiads from the peanut gallery about the degradation of American culture, the differences between 1950 and 2005 are dwarfed by the continuity. We've evolved, but are still culturally American. For a comparison, Casey Stengel's NY Yankees and Joe Torre's NY Yankees are different, but are still the Yankees.

I predict the same is going to happen by 2050. We'll have some new divisions, but they won't be on the current lines. And the dominant culture will remain the dominant culture.
