AN "INTERVENTIONIST'S" POPULAR OVERVIEW OF CAPITALISM
In case you're new to them, the "For Beginners" Documentary Comic Books by Pantheon were what existed before the "For Dummies" and "Complete Idiot" book series came into being. Profusely illustrated (more like a "graphic novel" than a "comic book"), they actually contained pretty reliable---and clearly-presented---information.
The text is by Robert Lekachman (1920-1989), who was a "serious" economist, and wrote books such as 'Greed Is Not Enough.'
In this 1981 book, he summarizes economists such as Adam Smith, Karl Marx, Werner Sombart, John Maynard Keynes, and Milton Friedman.
His non-free market, interventionist approach to economics is well-illustrated by the "Finale" chapter, "The Case Against Capitalism Reviewed."
He writes, "Even in the eyes of its defenders, capitalism has been deficient in two additional regards. There are very few competitive markets of the sort envisaged by Adam Smith and his followers. To an increasing degree, capitalist economies are directed by the entirely visible hands of monopolists, multinational giants and domestic oligopolists. And finally, the argument that competition, even where it is to be found, must enhance the public good is deflated by the ever-increasing environmental damage inflicted by externalities." (Pg. 170)
