I would point directly to the rampant and historical abuse that has plagued union leadership in the US, in a litany of business sectors as the primary reason. One of the largest in the country, the UAW, is currently going through quite a turnover as multiple layers of leadership are being indicted for everything from fraud to racketeering. Information about historical scandals is very searchable on the Googles.
