Read the book, then watch this doc if you can get your hands on it.
Looks like a good movie. This interview is a good example of liberals coming to understand that charity does not work, that systemic problems need systemic answers, that seemingly individual problems have national and global consequences – and have political causes, i.e., people in power are causing problems like poverty. Unfortunately simply clicking on something is not going to change anything and even voting will have little systemic effect. The next step for liberals like this is to realize our entire political system is corrupt and needs radical change through collective action. Unfortunately, not going to happen anytime soon.
