FWIW, I own and operate such a company and it is true, it is a very viable pathway to a good living. Yet, we struggle to hire good young talent, although I have recently been fortunate to be able to "stock up" on staff and for the first time in several years, would consider myself back to full staff...just as a recession hits.
But that is part of the fun of owning something like this I guess.
For many years...kids had it drummed into their head to "go to college...". So..."they" did. Now we have more people with more college debt than ever before and viable careers are still in a struggle to hire. It's almost like the colleges of America pulled one over on the population and sucked a bunch of money off of people or something.
(I am not hating on all colleges or those that pursue that path, but we need to move the proverbial pendulum back to a middle ground on that front IMO.)
