Whose armies murdered vast numbers in socialist China, Cuba, North Korea, the former Soviet Union? More were murdered by their own leaders than "your" armies.
Again, why don't those workers quit those jobs and join together to produce something useful they don't have to give to their evil bosses? That is exactly what my yard guy has done. He came here from Mexico, worked for landscapers to learn the business, and then started his own business and hires other immigrants to work for him. He now has over 100 customers. Of course, he is probably evil and pays himself more than he pays his workers. He also buys and maintains all his equipment, does all the payroll and taxes, recruits customers, collects the money.
In the case of the Soviet Union, eighteen capitalist armies attacked, destroying the working class on which the Revolution was based (Lenin had made a wild bet in starting things in a Country where the working class was, if very advanced, also very small). In China the Japanese and the Americans, as you know, though, as in Korea, similarly attacked, this was essentially a peasant, not a socialist revolution. I assure you that state capitalist armies are in no sense 'mine'.
Under capitalist dictatorship such as exists in most countries, the police state prevents most workers from doing anything much: only world revolution will produce any real freedom.
