I'm not sure I'm qualified to answer that. I'm not an economist, and these macro effects are just things I read about with interest.
The only thing that I would comment on, that your question prompts me to observe, and that is I think quite interesting and worth thinking about, is the effect of huge amounts of money being siphoned out of the United States and into Ireland. Ireland, as we know, has suffered severely in the economic downturn. There was a huge bubble in Ireland.
I think the implications of what the Irish did over the past 15 or 20 years by having low tax rates, which attracted investments from abroad, a lot of them from the United States, is well worthy of study.
Apart from that, in broader terms, I'm not really in a position to comment meaningfully on your question, sorry.
