Scores of political commentators have been recently suggesting, humorously but also earnestly, that we are currently living through a second "Gilded Age," an era in U.S. history when, as now, public concerns included rampant technological shifts, "massive wealth inequalities, hyperpartisanship, virulent anti-immigrant sentiment and growing concern about money in politics." (Edward T. O'Donnell, "Are We Living in the Gilded Age 2.0?" www.history.com/news/second-gilded-age-income-inequality ) The pushback against the first Gilded Age, of course, included what we now sometimes call the Progressive Era. Taking this idea as a starting point, our Roundtable will ask: What can current grassroots activists learn from 20th century organizing experiences about building a viable Left Alliance? Panelists will foment a broad-ranging discussion on subjects that may include the imbalance of wealth and power, migration and immigration law, environmental justice, reparations for slavery, interference in Latin American countries by U.S. moneyed elites, and current fights for gender and class equity of all kinds.
