Why do I have to be going anywhere? Mr Krugman was cited as saying that govt spending was inconsequential, and that turned out to be not quite the truth. That seems like something one ought to know.
As to what I think of increased government spending, I think that it is indicative of the problem - what Lenin sums up as Imperialism, or moribund capitalism, or as Marx says, capitalism in its dotage takes refuge in forms that are alien to it. What I don't think is that the growth of the state is a good thing.
On the other hand, I'm not looking forward to the Cameron cuts - speaking as the one that gets the child benefit cheque in our house. But much of the Brown spending that preceded it was subsidies to people I would happily dissolve in acid. Simon Jenkins, here, makes some good points (http://www.guardian.co.uk/commentisfree/2010/oct/05/quango-lobby-cuts-welfare-state). If I thought that Cameron really would cut the welfare to the well-heeled I would back him, but as with all things pro-capitalist governments do, the cuts will favour the rich over the working class. My enemy comes at me with a gun or a knife, why should I have a preference?
