I spoke with Jim Rogers directly in regards to this issue and he was against it as it would dry up liquidity. That was the last time I took him seriously. What we need as investors are men/women who invest based solely on company fundamentals and future earnings potential. And who can protect the fundamental values of US enterprises.
You can't afford to pay 5% then you better get back to work lassie. Point is one wouldn't invest in an equity unless he/she was certain the underlying equity wasn't going to at least provide a 10% ROI. That would ensure intelligence before the investment decision and a longer term investment time horizon. Something of which the majority of the market obviously lacks.
