State-owned monopolies exist in most capitalist countries, from operating prisons, to managing railroad or telecom infrastructure, to nuclear energy. The US may have fewer of those than say, the UK or France or Singapore, but I would not call those countries _communist_.

Not really. Different communist states have had different goals at different times. For example, nobody here is proposing collectivized agriculture (collectivized compute programming?), or purges of people perceived to be members of the bourgeois class.

God I wish at least 5% of people I see mentioning communism or socialism could properly define either of those terms.
