The idea in here that's super important is: Capitalism v. Communism DOESNT FUCKING MATTER. They instead phrase it in terms of "extractive" or "inclusive" which makes sense. You could have good central planning, or you could have a solid safety net.
What hit me recently: This is SUPER analogous to "best programming language," or more precisely, whether or not a language will turn out to be good is predictable at all. It ain't till you use it.
