Not in a physical sense -- we're not to guillotine territory yet -- but seriously... how much value do these people actually create vs., say, engineers, doctors, good executives in productive industries, skilled craftsmen, etc. People get all bent out of shape about pro athletes making too much, but it seems like the financial elite are by far the most overpaid people on Earth. Many of them seem to create negative value -- the systems that they run are liabilities.
