They create a false dichotomy in the minds of all who read the books on the topic who don't how trade really works (i.e. college freshman straight out of retard high schools). People actually think Capitalism is a system that was deliberately selected by nations and put in place. Like there was some kind of menu and nations all just picked the wrong one. That was never the case. Economics is simple when you break it down to ten people on an island realizing they can all specialize in certain tasks and trade with one another rather than trying to do everything themselves without specialized knowledge in each of those areas. It's a natural outgrowth of need and the wisdom of specialization and division of labor and the advent of money. But get enough poor, stupid people in one place like a city, and point out how some people are doing well and some people aren't, and they lap up this dogshit like milk and honey. It feeds their egos. Excuses their ignorance and their lack of self control. Gives them a scapegoat. And then buries them all together in a shallow grave.
