WASHINGTON — In the ongoing saga of the Affordable Care Act, oddly referred to by Democrats as the law of the land even as it is amended at will by presidential fiat, we are beginning to understand the extent of its war on jobs. First, the Congressional Budget Office triples its estimate of the drop in the workforce resulting from the disincentive introduced by Obamacare’s insurance subsidies: 2 million by 2017, 2.3 million by 2021. Democratic talking points gamely defend this as a good thing because these jobs are being given up voluntarily.
