A lot of people claim it to be purely economic, socialism vs capitalism. In this interpretation there are authoritarian and libertarian leaning people on both the right and left.

You will find out that on purely economic terms, the communist countries are remarkably similar to the classical Fascist propositions. They were mostly just forward with the same changes, possibly because the Fascists were killed after WWII and didn't have a lot of time to continue on the changes they started.

(But yes, maybe the Fascists would stop before reaching the same level, we can't know that.)
