So by making the system trade faster, they have made the market less stable and opened it up to outside manipulation.

Hardly what you call progress.

Outside "manipulation" has always been a force in markets. Perhaps HFT is making the system faster to recover to false information?

Or maybe it's just another zero-sum scheme for moving money from the rich to the very rich. Heck I dunno.
