On this episode of "The Federalist Radio Hour," Seth Kaplan, a senior adviser for the Institute for Integrated Transitions and a professorial lecturer in the Paul H. Nitze School of Advanced International Studies at Johns Hopkins University, joins Federalist Culture Editor Emily Jashinsky to discuss the rapid social decline found in American culture, explain why this decline is concentrated in "fragile neighborhoods," and explore the zip code-focused solutions that he believes can mend society.
