A couple things struck me:
- one of the issues in American history is the emergence of the market economy, when and how did it emerge? Here the family is mostly self-sufficient, but the father takes the hides of a couple sheep killed by wolves off to the city to sell, using an old motorcycle for transport, and bringing back a new plastic ladle. They also have a portable windmill/generator to provide juice for the electric light.
- Michael Pollan famously says we mostly eat corn in one form or another--these people eat milk in one form or another. (Nomads don't have gardens.)
- the family is torn between continuing its nomadic ways and perhaps moving to the city.
