Even if the HFT market is 100 times the smallest estimate, it's still a relatively small portion of the world economy, which is approximately $100 trillion. HFT is a fascinating intersection of finance/C++/JVM for competitive super-nerds. It happens to add liquidity to the market, as far as I understand. I am not demonizing it in any way.
However, it's not a significant portion of the US or global economy by any stretch. The argument over whether it sets or follows stock prices is mostly philosophical at this point.
