That free market capitalism is a good system that works. I grew up in a family that pretty much believed the opposite so I probably never would have become an entrepreneur otherwise. I mainly credit Milton Friedman's "Free to Choose" series for persuading me, as well as some of Paul Graham's essays.
HN is probably not the best medium to discuss this but the "Free to Choose" series I mentioned touches on those issues and is available for free on YouTube. It's still quite relevant today despite its age.
