Quote from bone:
Cool, I agree with you completely about the merits of a tax - and find it laughable that the progressives choose to fix everything with a new tax. My only real disagreement with your premise is in regards to HFT's somehow providing some sort of indispensable value to the markets - the liquidity they provide is not to be counted upon and is entirely conditional, just like most any other market participant. In fact, HFT's have been shown empirically through many third party reviews to distort markets during stress.
