HIgh frequency trading does provide a service to the financial markets as a whole despite what the media and government politicians will have you think.

OK, I'll bite. What benefit does the market *as a whole* get from the ability to do trades in 60ms rather than 120ms? (Hint - the fact you can extract money via more arbitrage transactions per minute is a benefit to the trader, not the market as a whole - if you extract $100M from the market, it came from somewhere....)
