Obamacare will induce people to drop out of the work force, a recent congressional study reported.

The Congressional Budget Office report, examining Obamacare’s effects on the economy, predicted that the U.S. workforce would shrink by 2.5 million people. The cause: Low-income people get subsidies when shopping on Obamacare’s health-insurance exchanges. This makes it easier for people to afford health care without a job or by working part-time.
