STEVEN GREENHOUSE covered labor for the New ¥ork Times for 19 years. Unions played a key role when the American economy created the greatest middle class the world had ever seen. Given how clearly unions improved the lives of hundreds of millions of laborers, why did workers allow corporations and government to weaken and shrink those unions? What can we do about it? Can our shared vulnerability to the pandemic and its destruction of the economy help us recreate the post-war experience of shared prosperity? We talk about greenhouse's latest book, Beaten Down Worked Up: The Past Present and Future of American Labor.
