Why did it take so long? It is over four years since the financial crisis began. Yet only now are anti-capitalist protests emerging, including at St Paul's Cathedral. So is this the beginning of a resurgent leftwing politics? I doubt it. Are the protesters raising some big questions? Yes, they are.
For this to be the beginning of a new leftwing politics, two things have to occur: first, a credible new ideology must emerge; second, some social force must march behind it.
In the 19th and early 20th centuries, the ideology was socialism and the force was organised labour. Socialism failed as a way of running economies. It did, however, succeed in establishing welfare states. Socialism is a conservative force, dedicated to defending entitlements built up over a century. Meanwhile, organised labour is only strongly entrenched in the public sector. This gives it the same conservative agenda: defending the welfare state. Strikes by UK public sector workers against the fiscal cuts will demonstrate this.
