In fact, all the powerful military equipment in the Soviet Union was developed and produced by scientific research and production personnel in a completely closed and semi-closed state. All technologies are kept confidential, and relevant technologies will not flow into any non-governmental organizations and enterprises. All the funds are also invested in one direction, and the only output is the weapon itself.
The Soviet Union has always given absolute priority to heavy industry with military as its core, and implemented policies of low income and low consumption and government welfare in other aspects. At the same time, the development of private economy and commerce has almost stagnated. The housing allocated during the Soviet period was still the six-story "Khrushchev Building" built by us 1980. The high technology of the Soviet Union is used in the military field, and real estate, education and medical care are provided free of charge by the state, so it is relatively backward. The export products that the Soviet Union can get its hands on are weapons and oil. However, the Soviet Union still has to target the United States in nuclear weapons, foreign aid, expanding its sphere of influence, and the space race. Therefore, it cannot be maintained economically and financially for a long time.
"Sustainable development" is always the golden rule of a country's progress. If we don't see this, we will suffer. The success of the United States lies in that it can not only make this investment generate economic benefits, but also recover it through the civilian market, protect overseas interests by forming military strength, earn it back through commerce and trade, and also make a virtuous circle in military science, education and economy. Therefore, the United States can hide it and hide it.
