The thing is, it is not a symmetric situation. Barring serious outliers, the worst that's going to happen to a company that can't find "the perfect candidate" is that they hire someone who is suboptimal. Maybe they even don't have the skills they claimed at all. Oh no, efficiency will be down and the execs' stock options might not be worth quite as much.
On the other hand, the worst thing that's going to happen to a typical job seeker who can't find a company that will hire them is that they will run through their savings—wait, do they have savings? this is America we're talking about, so probably not!—and be unable to pay their bills, causing them to become homeless.
So forgive me for having exactly zero sympathy for the companies that perpetuate this ugly arms race.
