The most productive period in human history was the 19 twenties, of the 19 fifti as the greatest rate of productivity growth. i think obviously we moved beyond the forms of social organization that pre existed capitalism. And even those nineteenth century institutions themselves were built on a process precisely expanding the market by democratizing the institutions within which the market lived. So i actually, the way i read the last 300 years is a gradual process of building greater and greater economies of scale and building democratic in tions to govern those.
