Gregory Clark on Social Mobility, Migration, and Assortative Mating (Live at Mercatus)

Conversations with Tyler

How much of your life’s trajectory was set in motion centuries ago? Gregory Clark has spent decades studying social mobility, and his findings suggest that where you land in society is far more predictable than we like to think. Using historical data, surname analysis, and migration patterns, Clark argues that social mobility rates have remained largely unchanged for 300 years—even across radically different political and economic systems.

He and Tyler discuss why we should care about relative mobility vs growing the size of the pie, how physical mobility does and doesn’t matter, why England was a meritocracy by 1700, how assortative mating affects economic and social progress, why India industrialized so late, a new potential explanation why Britain’s economic performance has been lukewarm since WWI, Malthusian societies then and now, whether a “hereditarian” stance favors large-scale redistribution or a free-market approach, the dynamics of assimilation within Europe and the role of negative selection in certain migrations, the challenge of accurately measuring living standards, the neighborhood-versus-family debate over what drives mobility, whether we need datasets larger than humanity itself to decode the genetics of social outcomes, and much more.
