That implies malice though, which I don't like. What's malicious about doing exactly what we agreed I'm paid to do, nothing more, and leaving when the whistle blows? In a job market where promotions are a pipe dream and equitable raises not far from it, why should I waste my time trying to impress someone that won't reciprocate?
Those people don't want "left wing change" because it helps the people that they hate as well as helping them. They'd rather shit their pants so we have to smell it.
