Thanks you for your thoughts! I really appreciate the discussion this game has generated. Much to mull over here as I have no formal background in economics (not even any micro/macro classes in high school).
I particularly like your idea of having imports as a way to use money to bridge gaps in your supply chain.
This game is probably just going to stay how it is, but I have put in a good amount of work on sequel to Command Economy that focuses on various socioeconomic classes instead of just proletariat. And this is some good stuff to mull over for that one.
Here is the code: https://github.com/BenEskildsen/CommandEconomy
Definitely fork it and make whatever changes you want!
