What industries would the state monopolize and why?

The state monopoly is to stabilize and consolidate the economic balance of the society, those western countries are stinking by that group of western capitalism capitalists. Do you know, the West what all capitalization is also known as personal privatization, in foreign countries to call an ambulance, can be paid after you have to pay a few thousand to tens of thousands of different service fees. Western prisons to go in you are a slave, Western prisons are capitalized, those capitalist-controlled prisons require inmates to sell their lives for the prison and no pay for hard labor, the worst conditions of food do not know what paste and maggots, to be more than how to save more than how to save. Drugs in the West are capitalized, bribing doctors to let them prescribe addictive drugs to patients with no moral boundaries, and the capitalists also threaten those doctors to sell drugs for them, and will prescribe them to you if you are sick or not. There is almost no universal health care in the west, the poor have to wait for death if they get sick, and health care is expensive as hell. Do you think capitalization (privatization of individuals) is good?
