The victories of the New Deal didn't happen just because suddenly everybody understood the brutalities of laissez-faire. This was a time, let's remember, of tremendous ideological ferment, when many different ideas about how to organize societies did battle with one another in the public square. A time when humanity dared to dream big about different kinds of futures, many of them organized along radically egalitarian lines. Now, not all of these ideas were good but this was an era of explosive imagining. This meant that the movements demanding change knew what they were against -- crushing poverty, widening inequality -- but just as important, they knew what they were for. They had their "no" and they had their "yes," too. They also had very different models of political organization than we do today.
