This reeks of principal-agent problems. HR departments at large firms are notoriously concerned with 1) folk knowledge about not getting sued (with a very tenuous relationship to reality, eg mgkimsal's comment), and 2) checking boxes. Since their actions have almost zero connection to outcomes, it's no wonder they play it safe / easy in hiring, and both firms and workers see shortages.
One way to start solving the problem is to make the department with the position responsible for filling it, either with their own man-hours, or via their own headhunting budget.
