The article paints a pretty negative picture of the present. While its true that there has been a convergence of factors that have caused much despair/desolation in most of America outside Tech/Coastal areas, this might simply be a rebalancing of the economy. Completely anecdotal of course, but most of the young Americans I see/meet are incredibly optimistic about the future, willing to work hard for their future, interested in other cultures etc. (But perhaps this is only because I live in a liberal city). It seems like Millennials are much better poised to build and contribute to a 21st century America.
At the risk of sounding incredibly ageist, it seems like its the older generation, the baby-boomers who are unwilling to retrain, unwilling to move, unwilling to accept or understand the new economy and world order. They seem to be yearning for a time when life was easier. While I can understand the sentiment, it seems to be producing incredibly toxic effects on the nation; we've seen the political ramifications, soon we might see social and economic ones as well.
