The school of thought that would most likely agree with uncle John is behaviorism.
Behaviorists believed that every type of action and behavior should be observed so as to be researched. If it cannot be directly observed, it doesn't require particular attention because it is not as relevant. Some famous behaviorists are Skinner, Watson, Pavlov, etc.
The silk road was one of the only ways to get goods from other countries in that time period. People traded food, spices, skills, etc. With the trade, countries could try new cultures leading to the spread of cultures.

Command economy is a system, where the centralized government determines economic components, such as what to produce, how much to produce and under what price to produce. It is an example of communist economies. Free market does not have an importance in this type of economy. Since central government is a sole competitor in command economy, <em>there would be no place for</em> limited private ventures.
