This, like other government inquisitions inquires has the potential to create more regulations. This inquiry can be picked up by nosy politicians and result in more regulations, which have a funny way of turning into a cartel for those with political connections — pull.

Thanks to lack of regulation, innovation and financial engineering, ETFs have democratized trading of exotic instruments such as currencies and commodities such as gold that were previously out of reach of retail investors.
