There are two reasons there's less protest:
1. The Old School who were such a pain in the butt in the 50s and tried to carry it on into the 60s had to be told where they got off - and that was two stops back.
2. Some of them carried on and became Thatcherites. They have about 4 months before the last of them retires, but in the mean time they put a generation into a position where nobody could afford to protest and NuLab locked them into that position.
But first there has to be a head of steam built up. It's happening, Dolphin Square and the failure to pass economic recovery down, this Spring could get heated.
