> Are there companies out there

There are absolutely lots of companies that have diversity and inclusion programs, and spend lots of money on these issues.

If your metric of success is "What are the successful companies doing" then you have to admit that basically every major corperate environment these days, has diversity programs, so by your own definition, they are important.

They have diversity programs, they aren't trying to hire exclusively women because they are cheaper. Those are two different things.

Also, nobody promotes diversity because diversity it reduces payroll costs. They do it because it allegedly produces better results.

> they have diversity programs

Ok great. Then you agree that diversity programs are good and competitive.

That is good enough of a concession to satisfy most people on this topic, no matter how you got to it!

So that's the success story. You demanded a success story, and at the very least, this shows that diversity programs are good and do produce better results, because basically every successful company does then.
