2. In order to get ahead of the curve, and also stabilise its neighbours, 3.5 seems too conservative so I would go with 4 or higher, if they really want to get the markets going. This sounds scary and who knows if they can afford it, but at least it is not 'unlimited everything', which is the Fed's current prescription. And I'm not crossing streams, as fiscal and monetary are pretty much the same thing.

Maybe more interesting is slow release, or 长跑? Like if, instead of an eye catching number upfront, a targeted, sustained release over the course of the next few years - a lot less sexy but a lot less wasteful, and more sensible?
