While I appreciate Mike Rowe's sentiments and general argument, this speech reminds of politicians who lament the loss of manufacturing jobs as America's backbone. Economists have regularly pointed out that as a country becomes wealthier and more educated, the share of the economy devoted to manufacturing falls. This isn't really a good or a bad thing, its just a reflection of how that country's resources fit into the global economy. This loss of manufacturing is only a problem when people are losing these jobs in a "race to the bottom" situation, much like Mexico and Asian countries during the 1990's.
However, I do acknowledge that the current education system frowns upon pursuing vocation degrees, when many of my friends would have excelled in these programs during high school if given the opportunity. The important distinction here is that we want jobs that are "skilled," not jobs that are manufacturing per se.
