I'm not sure they're not "doing the right thing". They can't hire who isn't here, and Utah is not a demographically diverse place. (Yes, they can recruit nationally, but for cost reasons, everyone starts by recruiting locally.)
I haven't seen any sign of any of these tech companies "shutting down minorities". From what I've seen, if the right candidate is a minority, they'll hire them without blinking.
I live in Portland, OR. It was actually illegal for Black people to live in Oregon until well into the 1900s. That is partly why so few Black people live here. My company has been trying to hire more Black people, but it is really difficult when none apply since so few live around here and all the other companies are also trying to become more diverse. If you are a programmer who is also Black, please consider moving to Portland.
Great message to put someone in a box "if you're black and a programmer we need you to fill our diversity quota so uproot your life and come here so we can virtue signal and post pictures of you on LinkedIn"
Hire good people, don't deny them on the basis of their immutable qualities. Don't pick someone because they look a certain way, but because they can do the work.
I have tried multiple times to hire a friend, who is black, because he is good (and not because he's black), and have failed every time because his cultural support structure is simply not there. That's not his problem, and honestly, it's not the Valley's problem, it's just a factr.
It took me a long time to understand this, but I realized, there's lots of places I wouldn't move, either, even for a good opportunity, because my expectations about the culture is some places and not others.
There is a rate of migration now and then, but honestly, there is a serious geo problem. Some people go where the jobs are (born here, but grew up out east), some won't, and there's nothing wrong with that.
