People who expect the current economic problems or possible worse ones to come to generate support for the would-be revolutionary left are almost certainly going to be disappointed.
To gain support the would-be revolutionaries would have to convince people that they have a realistic and desirable alternative. Who believes that they have?
People haven't turned and aren't going to turn to Anarcho-Wotsitry (or Reheated Bolshevism) just because times are hard and they dislike the status quo.
There are various very different things they might do. Possibilities include the following three:
- Stick with the current political system but with harsher policies. 'We can't really afford the welfare state now, can we? We all have to make sacrifices for the common good.'
- Amend the existing system to make it more authoritarian. This wouldn't be fascism, just: 'We need a strong government with a strong leader in times like these.' I recently listened to a young Russian explaining why she supports Putin and can imagine many British people feeling the same way about a 'strong' British leader.
- Give up on all sorts of politics - traditional, would-be radical, right-wing, left-wing - and focus on getting by in difficult circumstances by unscrupulous means. We had a little taste of that with last year's riots. If you live or work in a particularly grim part of a city or a particularly grim little town where many young and youngish people have given up expecting to work for a living or never expected to have the opportunity, you have probably already seen how people cope - and it's often not nice. (Obviously, insofar as people go for this option, they will generate among others support for the other two ugly options.)
I can't see any sign of the left gaining (except in the sense that of course it's possible that Miliband's Labour Party might win the next election and a Miliband Labour government might be slightly more civilised than a Cameron-Clegg government).
