Goldman can make more in a nano-second than most people would earn in several lifetimes.
Do thy even know what a "nanosecond" is?
A median person's earnings over a lifetime: a couple million dollars. Several lifetimes: say 10 million.
That's our nanosecond. So, Goldman Sachs would make more than 10 million billion per second, or more than one million million billion dollars per day (10^21) or close to a million billion billion dollars per year (10^24).
Reality: roughly 10 billion per year. In the long run, we're all dead. John Maynard Keynes
The argument is still misleading, but in a different way, as Goldman Sachs earns this money (legitimately or not) for their work setting up these trading systems, not just for the "nanosecond" of work.
