The tale of an 11-year-old's $5,000 stomachache reveals the Twilight Zone of hospital billing. The charges seem arbitrary if not indefensible.

As the U.S. Supreme Court ponders the fate of healthcare reform in the current election year, a study released on Thursday shows that one in four working-age Americans went without insurance at some point in 2011, often as a result of unemployment and other job changes.

Of all the street actions leading up to the NATO summit, the one that might seem most perplexing is a nurses’ rally for a tax on securities trades. Financial markets are pretty remote from hospital bedsides, you might think. Why would nurses get mixed up in an issue like that?

Justices Antonin Scalia, Anthony Kennedy, Ruth Bader Ginsburg, and Stephen Breyer did not have much in common during the three days of debate on the 2010 healthcare law before the Supreme Court March 26-28. But they did share one essential characteristic. All four will never have to worry about guaranteed access to healthcare.

The country's largest nurses union Friday afternoon pushed for a tax of Wall Street profits before a crowd of thousands in downtown Chicago at a protest aimed at the NATO summit. The National Nurses United rally concluded with an acoustic solo performance by former Rage Against the Machine guitarist Tom Morello, who's known for his union support.

A coalition of nurses’ unions is calling for a “Robin Hood” tax on Wall Street, which they say could generate up to $350 billion a year, in the first major protest ahead of this weekend’s NATO summit in Chicago. Their pitch: impose a tax of 50 cents on every $100 of trades of stocks, bonds, dividends and other financial transactions, which are not currently taxed. The U.S. would join more than a dozen other nations that already have a financial transaction tax.
