March 23 marks the ninth anniversary of the passage of the ACA, the Obama administration’s landmark health care reform bill. A lot has happened during that time, and it’s been a controversial ride. While the ACA is credited with opening access to health insurance to more than 20 million Americans who would otherwise have gone without, critics also blame it for increased health insurance costs and limiting health care consumer freedom.
