“We’ve had it backward for the last 30 years,” he said. “Rich businesspeople like me don’t create jobs. Rather they are a consequence of an ecosystemic feedback loop animated by middle-class consumers, and when they thrive, businesses grow and hire, and owners profit. That’s why taxing the rich to pay for investments that benefit all is a great deal for both the middle class and the rich.”

You can’t find that speech online. TED officials told Hanauer initially they were eager to distribute it. “I want to put this talk out into the world!” one of them wrote him in an e-mail in late April. But early this month they changed course, telling Hanauer that his remarks were too “political” and too controversial for posting.

Other TED talks posted online veer sharply into controversial and political territory, including NASA scientist James Hansen comparing climate change to an asteroid barreling toward Earth, and philanthropist Melinda Gates pushing for more access to contraception in the developing world.

TED curator Chris Anderson referenced the Gates talk in an e-mail to colleagues in early April, which was also sent to Hanauer, suggesting that he didn't want to release Hanauer’s talk at the same time as the one on contraception.

Hanauer’s talk “probably ranks as one of the most politically controversial talks we've ever run, and we need to be really careful when” to post it, Anderson wrote on April 6. “Next week ain't right. Confidentially, we already have Melinda Gates on contraception going out. Sorry for the mixed messages on this.”

In early May Anderson followed up with Hanauer to inform him he’d decided not to post his talk.

National Journal e-mailed Anderson to request an interview about what made a talk on inequality more politically controversial than, for example, contraception or climate change. Anderson, who is traveling abroad, responded with an e-mail statement that appeared to swipe at the popularity of Hanauer’s speech.

"Many of the talks given at the conference or at TED-U are not released,” Anderson wrote. “We only release one a day on TED.com and there's a backlog of amazing talks from all over the world. We do not comment publicly on reasons to release or not release [a] talk. It's unfair on the speakers concerned. But we have a general policy to avoid talks that are overtly partisan, and to avoid talks that have received mediocre audience ratings."

Update: 4:09 p.m.

In a May 7 email to Hanauer, forwarded to NJ, Anderson took issue with several of Hanauer's assertions in the talk, including the idea that businesspeople aren't job creators. He also made clear his aversion to the "political" nature of the talk.
