The original post poses a question that many peeps misunderstand.
As usual, helps to start by validating any silent presumptions embedded in the question:
What are the underlying facts that support categorizing Denmark or Finland as "socialist," i.e., government ownership of property and government controlled economy?
What are the underlying facts that support categorizing them as, say, "capitalist," i.e., private ownership of property and free market economy?
Is the form of government in Denmark or Sweden a dictatorship, representative democracy, or what.
Same questions for Venezuela.
Stay away from other people's opinions or summaries of the facts; they are often wrong. Instead, drill down to get them yourself, the sine qua non of a trader.
