A small group of grifters who know how not to self-destruct:
Mack was the elder, leader, mentor, and to a small extent the exploiter of a little group of men who had in common no families, no money, and no ambitions beyond food, drink, and contentment. But whereas most men in their search for contentment destroy themselves and fall wearily short of their targets, Mack and his friends approached contentment casually, quietly, and absorbed it gently.
How a shared passions turns useful objects into common goods:
Someone should write an erudite essay on the moral, physical, and esthetic effect of the Model T Ford on the American nation. Two generations of Americans knew more about the Ford coil than the clitoris, about the planetary system of gears than the solar system of stars. With the Model T, part of the concept of private property disappeared. Pliers ceased to be privately owned and a tire pump belonged to the last man who had picked it up. Most of the babies of the period were conceived in Model T Fords and not a few were born in them.

And how the orderly are sent topsy-turvey by the disorderly:
It was obvious that the wife was away the opened cans, the frying pan with lace from fried eggs still sticking to it, the crumbs on the kitchen table, the open box of shotgun shells on the bread box all shrieked of the lack of a woman, while the white curtains and the papers on the dish shelves and the too small towels on the rack told them a woman had been there. And they were unconsciously glad she wasn’t there. The kind of women who put papers on shelves and had little towels like that instinctively distrusted and disliked Mack and the boys. Such women knew that they were the worst threats to a home, for they offered ease and thought and companionship as opposed to neatness, order, and properness. They were very glad she was away.
