We're a dying breed. I see it in the auto & motorcycle industries, and with lawn equipment. Back when I was a kid, if you DIDN'T fix your own stuff, we thought you were strange, lol. Now it's a rarity to find someone that actually repairs their own stuff.
I won't say a majority of, but quite a few of my customers couldn't tell you what a piston is for, where it goes, or how it works. The younger they are, the less they know. My dad and grandpa taught me 90% of what I know. School (Motorcycle Mechanics Institute) taught me the electrical side of things. My grandpa taught my dad. It's the way it always was, up until recently. I think it's due to the unprecedented wealth increases over the past 70 years. People now have the money, and can't be bothered to learn.
I won't insult anyone that falls into that category. I just find it sad. If the crap hits the fan, to which all signs are pointing towards more than at any time in this Nation's history, a large majority of this population is going to be in for the damnedest rude awakening humankind has ever seen.
