Consider that the "liberal world order," as Biden has said the US must lead, has become consistently a "dumbing down" of the nation, and indeed much of Western civilization.
The call to recognize this is now decades old, with such as titles like "The Deliberate Dumbing Down of America" from 1999, to the idiotic university protests led by the likes of Jesse Jackson ("Hey, hey, ho, ho Western Civ has got to go"), to the continual changing measures for inflation and the worth of the US dollar, and more.
A compliant and gullible herd is sought, not a nation of independent thinkers and those who would ask "inconvenient" questions. This will not succeed in the long term, as one cannot long rule an empire of lies and lunacy.
“Lead by lowering” is the new mantra of our dear leader. Remember folks...the future scientists, designers, architects and engineers are being dumbed down to the point of imbecility so next time you drive over a bridge, hop on a plane or get on an elevator to ride 30 or 40 floors up enjoy what safety there is now in the competency of the designers and builders. The future will be too dangerous to leave home to venture into the world around you. Just fyi.
There IS positive benefit from a diverse group of colleagues. There have been instances in my line of work where the perspective of a colleague from outside the US made a difference. Indeed, I attended a seminar where all of us folks from the "developed economies" saw a risky project but the folks from the "emerging markets" saw opportunity. We hashed it out, professionally. It gave me a new perspective.
Years ago when I was working in Manhattan, Danny Glover made a stink about how a black man can't get a cab. I thought he was full of it. A few days later, when walking with a very good black friend, I saw it happen with my own eyes. My friend didn't rant and rave (I did), he made a comment, and tried to catch another cab. That, too, gave me a perspective I'd NEVER have absent my black friend.
Again, this was in NYC. You basically have more unforced diversity there than most other places. I believe my life has been enriched by that diversity. But that was voluntary. And it was organic. Seeing that cabbie blow past my black friend was WAAAAY more "awakening" than any stupid presentation by a white professional woman opportunist (more on her later).
Diversity cuts both ways....I also saw lots of leftists in NYC et al and, WOW they are messed up. Just like my cabbie experience hardened me, experiencing left wing violence but being told it's "mostly peaceful frustration" hardened me.
Many people never left where I grew up. They're not racist. They hold certain positions and views to which I don't subscribe. They'd probably feel different if they experienced my cabbie episode. They probably consider me a liberal in certain regards (though they probably consider me a scary right-wing radical on homeschoooing etc.). But we aren't at each other's throats.
In contrast, A LOT of the DEI stuff in corporate America is really stupid and FORCED. I've seen reprehensible presentations by opportunists like Robin DiAngelo that do nothing but make you check your email and tune out at best. That kind of nonsense isn't diversity - it's shaking the jar with the employee's being the red and black ants.
If I have a job opening in my business, I DO see value in canvassing a wide swath of candidates. But if the job is, say, for a pastry chef, I want to see if you can make pastry.
