Markets are hugely important. The problem is the size of the investment banks who neither supply the capital nor the equities, but due to proximity of the transaction are able to skim more and more cream out of the transactions and devote more and more brainpower to increasing that arbitrage. They have become so instrumental to the lives of the rich and powerful that they can completely destroy economies and be bailed out by tax payers the majority of whom have absolutely no interest in the solvency of said banks other than some extremely urgent, hand-wavy and fundamentally interest-conflicted warning of economic cataclysm. Obviously regulation doesn't seem to do much good because it just changes the rules which sends the investments games scrambling for new arbitrage opportunities which no regulatory agency has the resources to keep up with until its too late. Given the lack of political fortitude to combat moral hazard by forcing financial institutions to take their own losses on the chin, I think perhaps widespread and rabid investment banker hate could be the best societal medicine we have against the brain-drain to finance.
