To be really frank, I'm not sure there is a silver bullet. I'm not sure there's much you can do through the tax system or through regulation to change that.
The fact that we're sitting on about $625 billion of cash stuffed in corporate balance sheets is due a fear factor. It's a reflection of an uncertain world out there, of not knowing where the world economy is going. I would suspect, for example, that all the free trade deals we're either signing or pursuing are inherently good things because they give market access to other growing markets.
But I'm not sure there's a silver bullet that could come along and fix the problem. I think you really have to keep building confidence in the private sector. The fact that the American recovery is so strong is a good thing, so we're forecasting private investment growth next year following along stronger export growth.
I wouldn't necessarily advise going in, doing more fine-tuning and fiddling with the tax system.
