Kim, this is an interesting article.
Still there is a central part that I am not so sure of. It seems we "help" the middle class by LOWERING our return on investment. Of course every country is trying to raise its GDP, so we cannot do alot (easily) to raise it further.
so following your logic, its seems we should be DEPRESSING our available ROI. Is that really right?
And if we do it, I expect many rich will BUG OUT! Either they will literally leave, or just re-house their money off shore where it can still make strong return.
When I think about it this way, I am far less certain of your premise.... thoughts?
