In the early and mid 20th century, blue collar work was a proud occupation of a huge chunk of the population. Manufacture of world-leading products, unionised workforces, and the sense of lending a hand in a greater creative output all created an identity that men were proud to hold. I don't see it as a surprise that with the export of manufacturing jobs to cheap nations like India and China we have been left with a generation of lost men who refuse to work as feminized shirts in a call centre, back office or retail outlet.
The mainstream media puts the blame squarely on the individual people - saying they are immature, or lazy, or feckless. But these are symptoms of a greater decline. The western nations have been mismanaged in that they have chosen to turn away from manufacture for purely economic reasons. But they do not ever address the fact that for over 7,000 years, manual labour has been the primary method of making a living for most adult men.
Modern man cannot grow up, because there is nothing to "grow up" into.
