There are some surprising, & worrying thing in this interview.

With regard to the recovery & the over-estimation of how fast it would be, this does point to over-reliance on mathematical models that failed to take into account changing dynamics. Further concern is raised by their interpretation of why they have failed. While the "permanent" loss of capacities may explain part of the slow recovery, it does not explain all of it. A US recovery will, never again, under a global free-trade regime (that includes all manner of low wage (& low general compensation), poor labour & human rights, low environmental st&ard, non-rule of law countries that do not have the expense & complication of 19th & 20th century legacy infrastructure), be the same. A US recovery is now spread among many free-trade & near banana republic countries.Our share will be smaller than ever  & the "permanent" capacity loss was accelerated by these same countries. How did they miss that? No commonsense, too much model.
