Obviously, the people who own the automation will want a cut of the rewards, like any other business.
Obviously NASDAQ and electronic trading systems are a good innovation. But firms basically doing arbitrage or exploiting uneven network latency are not that economically productive.
> Inefficient market spreads and network latency is not worth remediating.
Well lowering market spreads is all about increasing the returns for capital, and incenctivising overfinancialisation. It's hardly curing cancer is it?
At worst it's actively harmful if you believe that the current state of turbo-financialised capitalism has its drawbacks.
> Network latency
Not really sure what you're talking about but surely spending billions of dollars to bring rtt latencies to 50 micros or whatever is not really a great use of money and top engineering talent. Again, it's playing an arbitrage game but not really delivering any value.
So the story here is that over the last twenty years they stole the lunch from the traditional market makers like eg banks.
Of course, they got rich in the process. But they started from relatively modest means, compared to the companies they took on.
Michael Lewis's 'Flash Boys' is an hilarious account of this process. Well, it's involuntarily hilarious, because to tell his story, Lewis needs to cast Goldman Sachs (!) and other big banks as the victim. See the rebuttal 'Flash Boys: Not so fast' by Peter Kovac for more insight.
