Tighter spreads and higher liquidity is not economically productive? I can see arguments both ways.
For me, it's about whether that higher liquidity is really worth using top engineering and mathematical talent.
Well, that's what we have market price signal for to decide.
Do you mean that high salaries indicate a demand in the market? Not much argument there, although it is sometimes the case that large companies hire talent purely to starve competition. But what I'm really questioning is whether those high salaries translate to value to society.
