Not OP, but I think of jobs like theirs as being about marginal utility - how much better off is the world if trades are executed .001 seconds faster? It seems that for a lot of jobs the answer is not at all.

The traders are better off than those whose trades are executed 0,001 seconds slower. That’s why they make it faster.
