Researchers at Goldman Sachs found that employment in the healthcare and social assistance sectors saw a marked increase after parts of Obamacare went into effect in 2012. The authors of the study concluded that for every one-percentage -- point increase in medical coverage, healthcare employment increased 0.45%. Based on the 5.4% increase in coverage nationwide since the law took hold, they estimated that it was responsible for about 500,000 new jobs. That represents 40% of the sector's job growth during that period. This new report is part of a growing body of research that suggests more federal spending on healthcare is actually a boon to the job market, contrary to what some of Obamacare's critics have asserted.
