Your example of the preschools is such a great one. You're bringing together children who have very little life experience, and haven't except for what their parents have taught them or they have observed, so they should be able to put aside their differences; yet these classrooms are some of the toughest to manage. Even at such a young age the diversity creates challenges, yet we're supposed to come together in the workplace because studies have shown it creates the biggest strides. It'll be interesting to see how diversity continues to change the marketplace now that it's here to stay.

Besides that, the grabbermint (at all levels) punishes organizations that don't make a sufficiently elaborate effort to kowtow to the deity of diversity. So do the media and various lefty pressure groups.

I think it's all poppycock from the get-go. People who differ very much in socioeconomic background, in ideology, in ethnic or national origin, seldom can work together well enough to accomplish anything at all. Figuratively, or often even literally, they don't even speak the same language. The amount of effort to overcome this roadblock would be uneconomic, but for the need to escape the ire of the grabbermint and of various designated-victim groups.

Oh, and by the way, if ads show people using and enjoying a product, and those people don't look and talk and act very much like me, I don't buy the product, because I figure it just isn't the kind of thing I would want or need. When advertisers pander to minorities, in order to keep from being boycotted by some pressure group, the ads become less effective in reaching the majority. Just sayin'.
