There is utility in things like futures contracts, a guaranteed price for grain is very important if a farmer needs to reliably pay a mortgage. There's significant diminishing utility in allowing that futures contract to be traded millions of times by algos or allowing huge profits by firms that can front-run because they have fiber lines and the best perf coders that see the farmer trying to make the trade before it hits other exchanges. Simple solution seems to be a financial transaction tax. No need for complex regulations, just decrease the incentives for working in the financial industry. Change will follow.
