I think the problem is that no one wants to do those jobs anymore because they think they're too good for it.  
  
 Plus, when you're told all your life that you need to spend $50K+ on a degree, and you finally receive it and realize it's almost worthless, you definitely don't want to do a job that doesn't require a degree just based on principle alone unless you're starving and have no choice.

No one wants to do them, or the going wage rate is not high enough for those jobs.
