Life isn’t fair. People don’t want to catch grief for it. They don’t want to be “gone after.” Part of the draw of hiring from these pools is you’re less likely to get folks who have the hang ups you’ve displayed in your post.
I really hate "life isn't fair" as an excuse to be an asshole. It is like excusing tripping a guy with a limp for being slow and prone to injury anyway. Just because it may be so is no excuse for making it worse.
Not to mention it demonstrates the exact flaws they are warning about but reality cannot be fooled. Those ignored talents will go elsewhere and the competitors will lack those particular flaws by necessity. And then they'll cry "Why did nobody warn me we were falling behind!" After doing their best to not to listen.
