No, CBO did not say Obamacare will kill 2 million jobs:
The Facts
First, this is not about jobs offered by employers. It’s about workers — and the choices they make.
The CBO’s estimate is mostly the result of an analysis of the impact of the law on the supply of labor. That means how many people choose to participate in the work force. In other words, the nonpartisan agency is examining whether the law increases or decreases incentives for people to work.
One big issue: the health insurance subsidies in the law. That’s a substantial benefit that decreases as people earn more money, so at a certain point, a person has to choose between earning more money or continuing to get the maximum help with health insurance payments. In other words, people might work longer and harder, but actually earn no more, or earn even less, money. That is a disincentive to work. (The same thing happens when people qualify for food stamps or other social services.)
Thus, some people might decide to work part-time, not full time, in order to keep getting health-care subsidies. Thus, they are reducing their supply of labor to the market. Other people near retirement age might decide they no longer need to hold onto their job just because it provides health insurance, and they also leave the work force.
Look at it this way: If someone says they decided to leave their job for personal reasons, most people would not say they “lost” their jobs. They simply decided not to work.
