One other thing that comes to mind - the players in the financial markets make so much money off that message-processing speed that it opens up a whole lot of options that may not be available to someone without those kinds of deep pockets. We're all still fighting Einstein, but the ability to just throw resources at the problem can surface some solutions that are out of reach when you manufacture something other than money.
I agree and scale is one of the reasons there's so much money to be made. The NYSE trades over $18 billion a day. A small edge can be exercised many many times.
