It is just so fun watching people rearranging the historical deckchairs to make sure that their tribe looks good and that the tribe of their opponents can be portrayed as those nasty, 'orrible, people over there. And so it is with this latest from Ha Joon Chang:
First, let’s look at the origins of the deficit. Contrary to the Conservative portrayal of it as a spendthrift party, Labour kept the budget in balance averaged over its first six years in office between 1997 and 2002. Between 2003 and 2007 the deficit rose, but at 3.2% of GDP a year it was manageable.
Quite: in those first few years Blair and Brown held to the spending limits that had been suggested by the previous, outgoing, Tory government. On the basis that if anyone thought they were the spendthrift Labour party of old then they wouldn't get elected. So there was, in there, a period of a public sector surplus. It's only after the second election that they ripped up that idea of fiscal restraint and became that Labour party of old again. So "balance" over the six years is actually a couple of years of Tory policy then spend, spend, spend.
And a deficit of 3.2% a year might be manageable: except of course it wasn't, was it? But more importantly it is a grave violation of the precepts of Keynesian economics to be having a deficit of any sort at that point in the economic cycle. If we are to take Keynesian demand management seriously (we don't, but let us do so arguendo) then yes, there should be fiscal expansion in the slumps. But the counterpart to that is that in the boom there should be restraint: a surplus, not a deficit. This is not to pay off the previous debt, it's not to create the borrowing room to provide the firepower for that next slump. It's because demand management means that you temper the booms as well as the busts. Given that the middle part of the Brown/Blair Terror was in fact the tail end of the longest modern peacetime boom then the public accounts should have been healthily in surplus. In order to temper that boom.
Chang is doing an edit to history here, to show that his tribe is better than the other one. Given the circumstances of the time Labour really were sailor-type drunken loons going on a spree with the nation's chequebook and don't let anybody tell you different.
