I can see knowing how to repair things but choosing not to: Maybe your high income means the time you might use to repair it could be better spent making money. Maybe you're busy with something today, and are willing to pay for the convenience of having someone else do it. Maybe you're getting old and just can't get on your back and do complex auto wrenching anymore.
But, I see people (mostly younger than myself) who never even learned to do even basic, basic home/auto repairs. I'm not talking brake jobs and kitchen remodels, I'm talking they can't change a flat tire, replace a leaking sink supply hose, or hell even vacuum their own apartment. They pay people to do everything. That's shocking to me. I kind of just naively thought everyone just gets taught this stuff when they're teenagers.
