A half-century ago, President Lyndon B. Johnson declared war on poverty. Since then, the percentage of poor Americans has declined, but more than 46 million still live below the poverty line today. That’s about 15 percent of the population. Whether the war on poverty was a success or failure is the subject of passionate debate and heavily ideological.

Critics argue those programs took away incentives to work and created an underclass dependent on government subsidies. Diane and guests talk about the causes and consequences of poverty in America.
