Keynes wanted govt. spending to invigorate the private sector of the economy, not keep govt. bureaucrats in obstructive, rather than productive, jobs.
Even John Maynard Keynes said “government stimulus spending” had very limited application.
I don’t understand that article at all. It sounds like total double-speak. Even if you accept that deficit spending in itself was not the cause of the current crisis, it can hardly be a good thing to have in the long term.
