Correct me if I&#x27;m wrong but Keynes also thought you should run a surplus during good economic times so you could run a deficit in the bad.<p>Now I know the necessity to do that has been dismissed by modern economists <i>but</i> actual Keynesian policies still have to be implemented by politicians who get elected. During recessions there tends to be a reluctance on the part of electorates to deliberately take on more debt which IMHO leads to Keynesian responses which are never quite robust enough to do the job they&#x27;re intended to do.<p>Whereas if you did actually run a surplus during good economic times or at least during <i>some</i> of the good economic times then the public would likely be a lot more likely to back a real Keynesian response.
