Is there really a labor shortage? What's your opinion?

About this article

I keep seeing article after article about how the trades are the future and that electricians and plumbers are the new millionaires etc. etc. I feel like there's maybe not a huge shortage and the market will be flooded and drive wages down? Or if it hasn't happened yet, it eventually will if we keep telling everybody to go into the trades? But I do think there is a shortage of supervisors of most degrees, whether foreman, QC, supers, etc... Am I seeing this right or am I mistaken here? submit...
