Maybe I'm wrong but it appears you are cherry picking a statement to support your Republican/ conservative ideology. In chapter 20 ,about 17:00, Chris states (not an exact quote) he believes that none of the issues in the crash course are being addressed on a national or international level. I take that as including both political parties and IMO the case that Republican policy would in general make things worse than Democrat policy, albeit not by much as the same powers are behind both parties , could easily be made. Throughout the crash course Chris points out that the problems are systemic and wouldn't be addressed, let alone solved by the status quo which both U.S. parties are committed to uphold.
