Most revolutions started in countries which were very underdeveloped and several - USSR, Cuba, China - ensured much more egalitarian societies with no-one now starving, illiterate or without access to medical treatment.
grannypauline, now we are getting to the nitty gritty. We are now agreed that the three countries you mention have genuinely tried to develop socialist countries, but they all failed, why?
1) One of the first things that has bothered me is that they all started with revolutions, nobody voted them in. Why?
2) All these countries then became one party states, with a government that crushed all opposition, even internal opposition from those who had different ideas on how to make their respective countries fully socialist. In other words they were the antithesis of democratic. Why?
3) All these countries, eventually failed and had to become mixed economies because they became economically and technologically backward (except in the military technology) field. I have described why this happens, in a post on p5 of this thread. It should be read again in conjunction with this thread. Why did these attempts at true socialism fail economically?
4) I admit this is a frivolity, but how would school fetes, car boot sales, jumble sales, craft fairs, or my personal hobby going round village hall auction sales and picking up trivia to sell on from a tent at antique fairs and other micro business/hobbies where money changes hands be handled in this socialist state. They would all obviously have to be state owned and managed, otherwise the socialist state would not be socialist anymore, but a mixed economy. How could this be done?
