Systems are not the sum of the individual actors who participate in them. Systems can influence and even control individuals back. Therefore, individual flaws in character or intellect are necessary, but not adequate to explain why systems are flawed.

Consider the future imagined in the movie "Idiocracy 2005". Society is collapsing because people are dumb. This is the explanation for all problems in that society. Capitalism, Resource extraction, environmental degradation, political corruption, and a rather authoritarian government are all blameless. The implication is that capitalism an authoritarianism are good if we could just be smart about it.

This is a big difference between left and right thinking. Republicans argue problems can be solved by reforming individuals; the police are good, there are just a few bad apples. Or that the right individual, at the helm of a system, can clean up all the issues with strength and resolve. This is the central pitch for supporting Trump.
