Chait goes another round but fails to link to Manzi's earlier response. Manzi:
The key practical point of the article is that I believe there is a different efficient frontier of smarter political action available to us than is currently being provided by our two major parties if we can try to see both sides of the eternal argument more clearly that is “the inherent conflict between the creative destruction involved in free-market capitalism and the innate human propensity to avoid risk and change”, that in our case is exacerbated by both “ever-increasing international competition” and “the growing disparity in behavioral norms and social conditions between the upper and lower income strata of American society”.
Manzi follows up again here.
