In From Head Shops to Whole Foods: The Rise and Fall of Activist Entrepreneurs (Columbia University Press, 2017), historian Joshua Clark Davis offers an unconventional history of the 1960s and 1970s by uncovering the work of activist entrepreneurs. These activists offered alternatives to conventional profit-driven corporate business models by opening up their own small businesses. It’s a fascinating account that challenges the mistaken idea that activism and political dissent are inherently antithetical to participation in the marketplace.
