I think it also has to do with the fact that they don't get any training from their Dads because--one for thing--they have no dads. I must say that it applies to the middle-class as well. When I was a kid I learned from my dad how to use an ax. He had had to learn to use an ax in otder to cut firewood. I didn't but used it to help clear brush on a lease. I remember an occasion where he was talking to someone while I was working. the fellow commented that he was impressed I could use an ax, because his son, a civil engineer, handled an ax "like a girl." Of course this puffed me up a bit--and made my dad grin.
Good for your dad. Sounds like mine. He was born and raised "country." He could do a heck of a lot of different things. Work on a car, build, electric, plumbing, you name it, he could do some of it. The old jack of all trades types. A welder by profession. Damn, I miss that man. He has been gone 31 years now.
