In communism*, the state owns the means of production. The state owns the factories, the farms, the financial systems. It has elections, but not free so don't need to be fair. Leaders cannot easily be replaced. The leaders' friends can, of course live outside the confines of the regime. There is no freedom to travel, often even inside the borders, let alone abroad.
Now contrast that with the scandis.** They restrain capitalism, tax for a fairer society and seem to have low crime rates or 'millionaire runaways'.
*Cuba, the Nokkies. China, (but they are playing the long march to capitalism in a'no we're not!' kinda way re foreign travel).
**Mentioned because they are regarded as social democracies. Americans want this called communism.
We on here should be honest enough to lay off the commie line (Spline et al), cos it's inaccurate, and detracts from the debate.
