Busytown bread from wheat to loaf
The book traces one loaf backward through a chain of separate workers. Each step is done by a different person with different tools, so a single everyday object becomes a readable record of divided labour.
What Do People Do All Day?

The town as a circle of exchange
Every worker makes or does one thing for other people, sells it for money, and spends that money on what other workers make. The farmer's income becomes the tailor's or grocer's income, which in turn buys the farmer's food. This makes a community a loop of mutual dependence in which nobody is self-sufficient and money is the connector between specialists.
Trace the hidden system behind ordinary things
Invisible infrastructure becomes understandable when you follow one flow end to end and draw every stage. Water can be followed from reservoir through treatment and underground pipes to the tap, and a letter can be followed from postbox through sorting to delivery. Following a single thing through its whole route turns utilities people take for granted into sequences they can explain.
Every role in the town is real work
The book gives equal visual weight to the road crew, the doctor, the sailor, the firefighter and the person cooking at home, presenting each as a worker whose output other people depend on. The rank or pay of a job is not the measure used. What counts is that the town stops functioning when any one of those contributions is missing.
