CHS comes out with fine essays time and again, and this is one such occasion.
Clueless economists are wringing their hands about the labor shortage without looking at the underlying causes, one of which is painfully obvious:
the American economy now only works for the top 10%; the American Dream of turning labor into capital is now reserved for the already-wealthy.
As a result the Smart Crowd is opting out of the conventional workforce's debt-overwork-deadend-treadmill. What clueless economists, pundits and politicos don't dare acknowledge is that credentials and hard work are not a ticket to middle-class security; they're a ticket to impossible workloads demanded by global corporations and high-cost lifestyles anchored by student-loan debt, high rents and out-of-reach real estate.
In other words, credentials and hard work are a deadend. Costs rise faster than your income no matter how hard you work, and corporations are ruthlessly extractive despite the bogus PR of "we value our employees": just as government only values its tax-donkeys after they're gone, corporations only value their employees after they burn out and leave the Corporate America treadmill for good.
