This discussion provides an overview of the healthcare industry and some of the challenges facing the healthcare industry today. The healthcare industry employs nearly 20 million people in the United States and generates about 10% of the private sector GDP. Jobs in this industry are in high demand and pay better than most other industries. Rapid change is underway in the healthcare industry due to forces like the Affordable Care Act ("Obamacare") and an aging population. Many of these industry-wide changes are impacting how physicians work and who physicians work for.
