Marc Andreessen and Andreessen Horowitz and other venture capitalists don't have a monopoly over the future (or current) direction of our society). Hell, they don't even have a plurality of control.
The things that Marc speaks of in this article that are fundamentally broken in the US are housing, education, and healthcare. I see new startups funded in the US every single week that attempt to solve these problems. In the end, though, they are bound by the regulatory constraints that American government imposes on them, and in these three areas, there is a patchwork of laws that is impossible to navigate if you wish to build anything meaningfully transformative. It is simply impossible for Marc Andreessen to deploy capital in a way that can accelerate the pace of housing development in San Francisco, or accelerate the pace of drug development in the US, or make public American high schools have a lower student-faculty ratio. The amount of regulatory capture in these long-running, slow-moving institutions is simply too high.
