It appalls me how few people will tackle what seem to me to be utterly basic repair tasks. I may be on the extreme end, but I think some people would pay someone to change a lightbulb in their house (and I'm sure a great many DO pay someone to replace a headlamp or tail light bulbs).
I'm trying to do my part, ensuring that my kids are exposed to the DIY/maker/hacker ethic/experience, and even went into to teach my daughter's kindergarten class the (very) basics of electricity and we "built" flashlights together (mostly, the kids did a life-scale real "electricity" game with banana jack cables to make a complete circuit and a light to light from a 12V battery and then they put stickers with their name on it around the batteries of pre-built flashlights with a bare wire to the negative terminal as the "switch".) That was 2 years ago, and the kids still talk about it sometimes when I see them at pickup. My son (3 at the time, 5 now) can explain from that how a switch works and that electricity "has to make a whole circle" in order to work.
This was the prototype version we made at home. The production version was more robust and looked better, but worked the same basic way.
