I agree, 2007 definitely changed a lot of "assumptions". But there were no "every main bankman stating out loud that aight, we're playing a new game now". Maybe 2007 started it, but 2020s, I'd say, is where everyone publicly acknowledged it?

> everyone had seen Japan fail to pump up its economy

Agreed about this, but I feel like everyone is watching Japan right now again. And I fear people will make wrong assumptions, given how its "economy is growing right now".
