The New York Times: What's Next For Health Care

The Associated Press: Nonprofit Insurers Struggle In New Marketplaces
A smorgasbord of options and lower prices for consumers were two of the chief selling points for President Barack Obama as he promoted his overhaul of the nation's health insurance industry, predicting Americans would see "competition in ways we haven't seen before." Companies were even started as a way to encourage innovation and competition, namely 23 consumer-run, co-op insurers created with the help of $2 billion in federal loans.

The health care benefits provided by large employers for over 170  million Americans may be in jeopardy because of costs related to the Affordable Care Act.

Put another way, the ACA will cost large U.S. employers between $4,800 and $5,900 per employee (Leo, 4/2).
