Now that Cathie Black has taken her controversial place as head of the city's schools, former Chancellor Joel Klein is getting ready to start his new job at News Corp. And it's becoming clearer why he left. Though he claims he had vowed to leave after two terms, and the media claims there were growing tensions with Bloomberg, Reuters is reporting that Klein could make upwards of $4.5 million at his new job, as opposed to $250,000 a year as Chancellor. However, most of that is bonuses; he'll have to scrape by on just $2 million/year in base salary.
