Well, not really. But if you view the Trillion Dollar Coin (TDC) meme, as I do, as a short-hand for the more general idea of using Platinum Coin Seigniorage (PCS), then yes, it can change the whole political game for progressives if President Obama dares to use it.
Literal TDC proposals would solve the debt-ceiling, but they won't solve the larger problem of defeating the austerity politics that is so close to getting the cuts to social safety net and important discretionary government programs that austerians have long sought. PCS game-changer proposals are the ones calling for, or analyzing the impact of, PCS options aimed at paying off the national debt and covering anticipated federal deficit spending for some years.
PCS options of that kind change the game of fiscal politics by removing the issue of austerity from fiscal policy considerations. With this kind of PCS the national debt and the debt-to-GDP ratio go away as matters of concern. The focus of fiscal policy then becomes the impact of specific policies rather than some overall deficit or debt reducing target. The issue in fiscal policy then becomes public purpose. It becomes what specific impacts, including inflation, and full employment, are anticipated from passing specific legislation, and whether or not those impacts are in line with public purpose. But, when the national debt and the debt-to-GDP ration go away as matters of concern; then the issue of the deficit viewed as something that is draining a limited supply of financial resources goes away, also, because people will understand that using PCS to cover deficits ensures that the US Treasury can never run short of its own fiat currency.
I'm sorry to say that there are few posts of this kind, relatively speaking. I'll list and link to some of those posts later. But first I want to point to what some in the MSM blogosphere are saying right now. Read more about Wake Up Progressives: the Trillion Dollar Coin Can Be Game-Changing!
