The workers who had the doctor dragged away were awful. So were the airline managers who encouraged severe overbooking.
The sad, frightening reality we may forget when we laugh is that, if we are somehow involved in financial services, or plugged in to policymaking well enough to know (vaguely) what a budget reconciliation measure is, we have probably helped overbook the world's retirement benefits plane.
United Airlines had a few more passengers booked for a particular flight than the flight could handle.
