Exactly - if you don't understand a system, how can you fix it? You risk making it worse, rather than better, or shunting the problem elsewhere, but not really fixing it.
The sentiment seems to be that "we" need to somehow control these prices and markets, which has worked horribly in the past (and present).
The creation of the index isn't the problem. Wild speculation is. When you speculate the wrong way, you need to lose. But the precedent has been set --not only on the top level with the huge banks, but with main street citizens speculating on second homes and mortgages-- that the bet should be upside only.
