The resulting law — born at the very moment the economy was bottoming out — ultimately came down on the side of saving jobs. It conceded many cost controls in favor of softer measures. And in that respect the decision paid off: The industry has gained nearly 2 million jobs since the ACA was signed into law in March 2010. More people — 15.5 million — now work in health care than live in the state of Ohio. Employment in the health insurance industry, which had fallen since the recession, jumped nearly 9 percent from 2012 to 2013 as millions of Americans became newly insured. Based on job numbers, no sector is healthier than health care.
