One of the biggest political debates regards the best type of economic system, which usually boils down to capitalism vs socialism.
Are there other kinds of economic systems, aside from more "primitive" kinds, like barter?
To put my question in perspective, I think of economic systems as a continuum that looks something like this:
communism | socialism | "mixed economy" | capitalism | "free market capitalism" (anything goes, rampant corruption and inequality)
So "mixed economy" would be a combination of socialism and capitalism, rather than a distinct economic system.
But that's just my opinion. There may be views that are radically different than mine
