Dylan Matthews and Jerusalem Demsas are joined by Nick Buttrick (@NickButtrick), a psychologist at Princeton, to talk about interstate mobility in the US (or the lack thereof). They talk about why it is so hard to move; why some of those reasons, Jerusalem argues, are arbitrary; and what an immobile population means for American culture.   References: Jerusalem’s article about why it’s so hard to move in America Nick Buttrick’s research: The cultural dynamics of declining residential mobility A paper from David Schleicher called Stuck!
