Burnwinter Thing is, calling this new precarity a result of the failures of the historical left gets it backwards: we only understand with certainty that this situation sucks because of what was achieved historically.
Maybe. Maybe. But I remain unconvinced that we are doing anything but accept the terms of capital to win relatively minor concessions for a privileged few. I also remain unconvinced that life was so horrible before capitalism that its terms cannot be more systematically challenged. What bugs me is the idea that we should be grateful for a 40-hour work week because it could be worse, when it currently is so much worse for so many precisely because capitalists can afford us to have that 40-hour work week at the periphery's expense. That doesn't seem like a victory for the left, but for capital, or perhaps more precisely, the dynamics of an exploitative global labor market.
