Communism differs from Capitalism in that the Capitalist free market offers more choices. Communism has too much top heavy control, so choices become limited and they are not your choices. There is too much top heavy skim and waste. The free market spreads out the supply for more choices.
If you went to a Super Market in a Capitalist county like the USA, the choices of items to buy are endless. Fresh produce from all over the world. There is something for all choices in food.
In a Communist country the Minster of Food may decide only certain products will be available. Everyone gets to stand in long lines hoping the powers to be grew enough food this year.
Communist leadership will never take a vote and asks the citizens what they want and then try to make it available like they do in the Free Market. This would undermine their power, making them the butler and not the overlord.
In the free market, good customer service is key, which means the owner and his employees do not mind being a good butler. This support role works out for the best, for everyone. A good Staff may also also be a wealth of knowledge and will bring in new products, if these are requested.
Picture if Big Government treated its citizen like customers in the free market, who are buying services with their tax dollars. Agencies that have poor service, will go bankrupt while those who give good service will grow. The RMV; registers of motor vehicles, is more like the top heavy Communists. They can give bad service since you have no vote or other option.
Say we made the services of the RMV, part of the private sector using Capitalist techniques; lower cost and better services. Could the current Communist model RMV, compete if customers had more choices? Thew answer is no. This is why that type of service model, can only last if it stays a top heavy monopoly.
