Going back a few decades, or so, I noted the teenagers who had to pay for their own tires learned to respect their equipment better than the silver spoon crowd.  When the latter did come to appreciate the cost of things, they tended to be stingy with their money, finding excuses to not contribute.

A buddy took for granted the wood I had in my shop. Especially if he knew I'd acquired and processed it myself. I took him to town and we shopped for a bit of walnut and mahogany. He developed a whole new respect for what he'd been taking for granted.
