Rich but ignoramuses?
One evening in the apartment complex where I am (once had a home, fell on hard times) I found four white rednecks (complete with construction company tee shirts, ball caps, and twelve pack of Bud Lite) changing the transmission fluid on a chopped up truck one pint at a time with various brands of ATF. Taking three hours to do it.
If you’re saying that dufuses come in all races, colors, religions, and flavors, I agree wholeheartedly!
