Government deficit spending is a central point of controversy in economics, with prominent economists holding differing views. The mainstream economics position is that deficit spending is desirable and necessary as part of countercyclical fiscal policy, but that there should not be a structural deficit: in an economic slump, government should run deficits, to compensate for the shortfall in aggregate demand, but should run corresponding surpluses in boom times so that there is no net deficit over an economic cycle – a cyclical deficit only. This is derived from Keynesian economics, and has been the mainstream economics view (in the Anglo-Saxon world especially) since Keynesian economics was developed and largely accepted in the Great Depression in the 1930s.
I have never argued for structural deficits. I have maintained that now is not the time for drastic cuts in spending. I believe we can cut or move money away from the defense dept.
