I disagree that this is the only way to eliminate this problem. Companies could loosen promotion criteria to be more in line with what external candidates bring. Ultimately the cost of lost knowledge and backfilling is quite high, and could easily justify faster promotion cycles on a monetary basis alone.

Even if some of them genuinely get promoted before they’re ready and wash out, you’re not really that much worse off than if you’d lost them before. Besides, there’s always the risk that your new hire is unprepared too, which is a much harder thing to quantify.
