The author is referring to recent reports from the National Foundation for American Policy. I was unable to find much independent information about this organization. Here are some remarks about NFAP from the author:
Probably the most debunked economic fiction spinner of them all, the NFAP, is used. The NFAP is also these very multinational's personal white paper spin machine.This report provides more evidence that the middle class in the US is being abandoned by the ruling class, and thus, is increasingly losing their support. This is a dangerous development for the ruling class.
