I have several friends with degree's, one with a PHD and i myself have umpteens of trade related quals and neither i nor they have ever been asked to prove it. I know lots of people , including myself that are where they are today from who they know, not what they know. And besides, since any tom dick and harry can get a degree in anything these days there value has plumetted, as with anything. Flood the market with cheap and easy degree's and there value declines. Just ask the person that serves you next time you go through the drive through.
I think apprenticeships are the way to go, the way i went. I have loads of little teaboys with nice pieces of paper, doesn't make there brews taste nicer
