There's a huge fallacy at play here. Somehow, it seems, there's an underlying assumption that the capacity to be a good air traffic controller is rare. That the capacity to be a good pilot is rare. That most positions we could choose from require rare and fantastic in-born talents.
If you look around with a critical eye, you will quickly find that that is just false. Most people we each run into each day do something well. Not everything, of course, but often several somethings. That's a large hint that what makes us special and capable isn't some capacity that is rare. Instead, it's the opportunity that is presented to you that mostly governs what you're good at. And we, in this group, playing with obscenely expensive toys, are selected mostly from those that have had ample opportunity.
So there's a bit of an echo chamber.
Bringing up the "bar" every time minority hiring comes up is implicitly biased. It's a claim, however subtle, that minorities cannot meet the bar that us white males can. Guess what? They can and do. The "bar" is not what is keeping out the underrepresented.
Equal opportunity laws are, today, an admittedly blunt tool. They direct that, if you have two capable people to select from for a position, pick the underrepresented one until they're not underrepresented any more. There is plenty of talent out there. There is no need to lower any bar. There is a need to even out opportunity.
Where I'd like to see effort paid is to more accurately measuring opportunity. The current lever of race or gender is a bit blunt, as noted.
And, full disclosure, an evening of the playing field would have done me no favors. I'm white, I'm male, I'm straight. I come from two college educated parents who stayed together till death did them part. I grew up middle to upper-middle class. One of my parents had ancestors come over on the Mayflower. I'm able to play here because I had all that and because I worked hard and made some lucky decisions. I hold no guilt over what I have. I would just like to see our society not withhold what I had from anyone.
Also, full disclosure, I didn't read the article because it's behind a paywall and I don't subscribe to the WSJ. So, this is in response to what's in this thread, not the article.
