Now if I understand the quadras correctly, it's the Gammas who recognize economic opportunity, and the Betas who mobilize to achieve it. How can we apply this to the current economic problems afflicting the West?
First of all, ISTj could resist attempting to reorganize for profit. This would cause debt to rise, but jobs would remain until the excess inventory had been sold. A job-full recession that would last only as long as the excess inventory does. Governments could offer tax rebates to corporations for as long as their inventory remains in surplus. To account for the declines in production, companies could send their workers home (with pay, perhaps modestly reduced), or find alternate uses for them. This would give the companies incentive to sell off their inventory as quickly as possible despite the lower taxation.
So long as the economy is held in a freeze-frame until the inventory falls, there will only be a momentary pause of a few months before production universally resumes. The trick is not to reorganize.
As for the housing problem, there will definitely need to be some government intervention on that count.
