There is also some outright "pickyness" coming from the younger generations against work that's seen as manual and unsophisticated, at least I perceived this in the architecture school I went to for a number of years. I remember very clearly many professors lamenting the fact that with each passing year the student body grew more reliant on technology and computer-assisted crafting and grew less interested in manual handicraft.

It's going to sound cliche but younger folks are more attracted to work that looks attractive. Everyone wants to be able to tell others at a party that he works a respectable job for a well-known company. The media doesn't idolize craftsmen and truck drivers as much as tech whizzes, so something drops under the radar.
