MEGAN MCARDLE: “If you want to know why I am no longer a lefty, just read this series on MyDD about PIRG, the organisation that supervised my transition from ultraliberal to libertarian. I have never worked at any organisation, including the Catskills hotel that basically used foreIgn temporary labour in sweatshop fashion, that treated its employees as shamefully as PIRG. People talk about workers being disposable, but no other business model I have encountered depends on its employees having an average tenure of two weeks, the better to funnel their lost wages up the hierarchy to god-knows-where.”
