This is really only true for certain locations. Also, to be your own boss means you have to understand how to obtain the licenses, start the business, etc. Many of the people who could do the actual job may not be able to the overhead to be their own boss. The companies do background checks and most don't really train. The overall percentage of these blue collar jobs are a much lower percentage than they used to be. So there's more competition. Good luck getting hired with even a minor criminal record or it you don't have a driver's license.

I would quit my job today if I could make $100k
