Diversity is good for companies. Diverse companies are more profitable.
Regardless, your clever analogy doesn't apply. Companies are welcome to be political in their own environment. They own it. Employees are not. They're employed at-will.
Maybe, but that doesn't immunize them from criticism, especially when they purport to value diversity and free speech but silence critics.
Anyway, the financial benefits of diversity are almost certainly overstated. I don't know why we can't just say, "we're hiring diverse people because we think it's the right thing to do".
In a thousand years archaeologists will write papers on our civilisation and the god we worshipped called Market. About how we obeyed the laws of Market, appeased the Market when it was unhappy, and how we had faith that Market could solve all problems.
As a society we've been trained or perhaps tricked to suppress our sense of justice and fairness In Gabor of money.
People are hesitant to publicly say that the right thing to do is the thing that should be done so they bring financial arguments into it.
Hence the studies promoting the idea that diverse companies are more profitable, as if that should make any difference. It's a sick obsession with viewing just about everything through a financial lens even when money shouldn't come into it.
