The 1930s was a time of massive organizing, strikes, union activity, and dissent that forced FDR and the New Deal to the left. 2009 does not provide us with such inspiring levels of resistance.
If the 1930s can teach us one key lesson, it is the need to organize. Nothing changes when people do not engage in the long and difficult work of building a diverse, multi-cultural, working class movement from the ground up. This includes artists.
