There is a shortage of plumbers, electricians, welders and other skilled trades people due to the extremely low number of people going into the field. Here is an article describing the problem
What I am saying is that we need to get a balance. Don't dump everyone into trades. Put more people into trades, and less people into college programs that have little to no workforce demand, and/or help the people that drop out of college. It is a societal problem that has made way too many people, especially in major urban areas (talking to you Chicagoland) feel that trades jobs are beneath them. Just because I have a BS in Electrical Engineering means I know how to automatically safely wire a house (though I could read up on it) or do a good job doing it. We need skilled trades people and not have the people driving their luxury cars look down on those people.
