An advanced society is marked by commerce and taxes.
First, nations trade with each other. They had to develop a strong industry that manufactures the right number of products so the country can export an import on a regular basis and supports a strong economy. Once the trade is formally established, countries can charge taxes on imports, for instance, or apply other forms of taxations in order to generate more income and that money collected by taxes can be applied in continuing social or infrastructure programs that benefit the citizens.
