So the austerity drive in Britain isn’t really about debt and deficits at all; it’s about using deficit panic as an excuse to dismantle social programs. And this is, of course, exactly the same thing that has been happening in America.
But what became clear in the policy debate after the 2008 crisis was that many economists — including many macroeconomists — don’t know the simplest multiplier analysis. They literally know nothing about models in which aggregate demand can be determined by more than the quantity of money. I’m not saying that they have looked into such models and rejected them; they are unaware that it's even possible to tell a logically consistent Keynesian story.
In the end, those of us who expected the crisis to provide a teachable moment were right, but not in the way we expected. Never mind relearning the case for bank regulation; what we learned, instead, is what happens when an ideology backed by vast wealth and immense power confronts inconvenient facts. And the answer is, the facts lose.
How did we get to this point? It’s the logical consequence of three decades of antigovernment rhetoric, rhetoric that has convinced many voters that a dollar collected in taxes is always a dollar wasted, that the public sector can’t do anything right.
As a result, everyone in the political class — by which I mean politicians, people in the news media, and so on, basically whoever is in a position to influence the final stage of this legislative marathon — now has to make a choice. The seemingly impossible dream of fundamental health reform is just a few steps away from becoming reality, and each player has to decide whether he or she is going to help it across the finish line or stand in its way....
