People in corporate environments are going to need a new framework for understanding what the numbers mean. The problem with how corporations have responded so far to trends in multiculturalization is that they're looking at the new data through their old filters. When you look at population growth among ethnic groups through the old filters of a fixed mainstream culture, you miss what's going on with the way ethnic and mainstream cultures are evolving. The assumptions in the classic model for understanding the effects of multiculturalism draw from a static idea of mainstream culture. Imagine an unchanging shoreline, with the waves of ethnic population growth washing in.
Corporations fail to understand that the island has sunk.
American culture has ceased to be static, while still, most ethnic-marketing officials at companies assume a static mainstream culture. The issue has always been culture, not numbers. Corporations, more often than not, miss the point that you have to understand values before you can create value. Evidence of how dramatic a change we're going through is the fact that it's no longer necessary for immigrants, nor even first-generation Americans, to learn English to function and thrive in this society. The acculturation models, if anything, are reversing.
