Markets and Trust

"[Y]ou’re not going to specialize in a particular trade — maybe you make steel plows — unless you know that there are other people who are specializing in other kinds of trades which you need — say food or say materials for making housing, and you have to be confident that you can trade with them or exchange with them and get the other things you need. There’s a lot of risk in developing specialization because you have to be confident that there’s a market there that you can engage with."
