Richard Walker is a retired professor of geography (he's not so fond of the term "emeritus") at the University of California, Berkeley. As he's described on the UC Berkeley website: "An enduring thread of Professor Walker’s thought is the logic of capitalism as an economic, political and social system, and its geographical evolution." He has written extensively about the state of California, including its agricultural and environmental heritage.
In "Picutres of a Gone City: Tech and the Dark Side of Prosperity" Walker, a lifelong resident of the Bay Area, discusses the harsh realities of life for many in our communities, especially those at the bottom of the economic ladder. He presents some solutions to our housing crisis, and explores the downside of the tech revolution that has transformed the region.
Discussing Walker's book, Jason W. Moore says: "Drawing on a lifetime of research, Richard Walker dismantles the mythology of the New Economhy, placing its creativity in a long history of power, work, and struggles for justice."
