An outline of the summaries of the systems of economics (capitalism, socialism, communism, mixed economies), along with their most common subsets (free market, social market, etc), the main questions they are trying to answer (means of production, profit and wealth capture, gov't role) would be critically important at this time. It seems to me that terms like socialism and capitalism are thrown around without meaning in the news. A chart of which countries are currently operating under which schema, and which politicians are advocating which types would be bonus. (Does Sanders really want Socialism or does he mean social market economy / Rhine capitalism? etc.) Thanks!
