From a business perspective, did it work? Was the team more, less, or equally effective than one where you didn't expend the time and expense of hiring a more homogenous group? Was turnover better or worse?
I know you can't absolutely know the counter-factual, but I've always wondered this. Incidentally, when I was a young man and CS major, I changed majors and went into a different field because I wanted to be around more women, but I've never known if being outside that kind of monoculture actually is better for the business or not.
Is the business perspective the right one to go with?
Let's say it's legal to discriminate on race in hiring in the US. Then a Japanese restaurant hires only Japanese workers because they find customers prefer it. Do we want to have this?
The purpose of our state is to provide for its citizens. So we decided to use a market economy because it seems the most efficient way to do that. But we make up the rules that it runs by and we can change the rules as we see fit.
So it seems now we are saying DEI is not a good rule. Can we make a better rule or is the goal of that rule not good?
There are multiple axes upon which something like this can be evaluated. I'm not against us as a society collectively deciding we should enforce rules that may be counter to business logic (e.g., child labor laws to pick something uncontroversial).
When something is more controversial, it's common to look at the business case. It has commonly been argued that 'diversity' is good business even disregarding any desire one may have related to restorative justice.
Put simply, if it's good business and good morals we should do it, if it's bad business and good morals or good business and bad morals, we have to weigh the balance of it (bad business can lead to morally bad outcomes, like layoffs), and if it's bad business and bad morals we ought not do it at all. I was just focusing on the business case under the assumption that the poster believed it to be good morally.
