It's from a 2006 article by David Sirota.
Mr. Obama Goes to Washington | The Nation
The quotation in context
Obama has a remarkable ability to convince you that his positions are motivated purely by principles, not tactical considerations. This skill is so subtle and impressive, it resembles Luke Skywalker's mastery of the Force. It's a powerful tool for a Democratic Party that often emanates calculation rather than conviction. "I don't think in ideological terms. I never have," Obama said, continuing on the healthcare theme. "Everybody who supports single-payer healthcare says, 'Look at all this money we would be saving from insurance and paperwork.' That represents 1 million, 2 million, 3 million jobs of people who are working at Blue Cross Blue Shield or Kaiser or other places. What are we doing with them? Where are we employing them?"
There's genuinely a lot of people working those overhead fake jobs, I remember Bernie didn't talk a lot about that which if you're uncharitable means he wasn't serious about doing single payer, and if you are charitable he means he recognized it as a huge political problem that there was more benefit in ignoring until you actually got the power to do something about it.
Basically "I'm not gonna talk about how so many of you will need to get real jobs, with my help of course, until I actually can do something about it"
