Suppose there is a street full of car dealerships. They sell cars for $10,000. It will not be any surprise, that they only observe money in $10,000 chunks. In fact, they have intended this.So suppose there are some popcorn vendors, and some hookers, and some other people. A car dealer takes his $10,000 from a sale, and walks into the street. He spends a few hundred on a hooker, a few hundred on clothes, buys some popcorn. The popcorn vendor saves up and buys a coat. The coat salesman also pimps for the hooker. So the coat salesman saves up, and walks into a car dealership with $10,000.So is it a single $10,000 chunk, or is it lots of pieces of money, that travel different paths?It will always arrive as a single $10,000 piece, if a dealership selling cars for $10,000 is your means to observe money. But which car dealership it arrives at, will depend if it flows through the hooker and the popcorn vendor, or the grocer and the clothier. The more complicated the topology, the more interesting the pattern of arrival of 10k rolls up and down the street of car dealers.Whereas if there were only one vendor in the whole city, then all money from all sales would flow to his single favorite dealership, which he has his shop in front of.
