The PMP – How It Ruined Project Management

In a broader scope, if I may: If we suppose there are people that are undervalued by the dominant market process, where's the arbitrage -- teams seeking that talent out and applying it for gain (and competing with one another to correct the price)?

Is it the case we have a bear market for human intellectual effort and "The market can stay irrational longer than you can stay solvent" -- the rare organizations capable of skilled-labor arbitrage can't form and thrive?

Or, are humans just that much less useful to organizations (and capital) than we are used to suppose (and than they are currently compensated)?
