From a Benjamin Bratton Critique of TED:
Communism in theory is an egalitarian utopia.
Actually existing communism meant ecological devastation, government spying, crappy cars and gulags.
Capitalism in theory is rocket ships, nanomedicine, and Bono saving Africa.
Actually existing capitalism means Walmart jobs, McMansions, people living in the sewers under Las Vegas, Ryan Seacrest … plus – ecological devastation, government spying, crappy public transportation and for-profit prisons.
Our options for change range from basically what we have plus a little more Hayek, to what we have plus a little more Keynes. Why?
An excellent question...
