Superstructure is the state, which is also known as the Country or Nation.
Substructure is the economy.
Therefore, in any country, those who control the Substructure equally control the Superstructure. Those who control the Substructure are "Capitalists", they use the country to do business in the international level, so the country Became a collateral in the international loans and others.
Great forum!! I think in terms of democracy, banks control the economy.
governments control the state(law and land)
