"At <a href=""https://www.youtube.com/watch?v=OJQepiqSWvg&amp;t=19m30s"">19:30</a>", something to consider is not the current state of market processes but their trends through time and the solution spaces that are possible. Farming/agriculture has had many thousands of years of worldwide development, modern healthcare and education haven't. There is no immediate market solution to something like education because no one really knows how to do it right. The upside with the market approach (i.e charter schools) is the potential for evolution, for searching a state space and thus allowing optimisation.
