Entrepreneur Steve Case and "Hillbilly Elegy" author-turned-venture-capitalist J. D. Vance have taken their investment mission on a bus tour they’re calling “Rise of the Rest.” They are travelling around Middle America, identifying and rewarding entrepreneurs who exhibit the kinds of talent and ingenuity that many mistakenly believe only happens in Silicon Valley. What are they learning about the US innovation economy? Joining them in discussion is Katie Couric, who herself has been crisscrossing America to find out what makes us tick.
