Taxing those with insurance to pay for those without

As a way to pay for the plan to expand health coverage to the nearly 50 million people who are now uninsured, the government is considering taxing people who already have the most expensive health benefits, as provided by their employers. By one Congressional estimate, it could yield $100 billion in revenue over five years. And although President Obama criticized the notion last year when Senator John McCain promoted it during their presidential campaigns, the concept now has some support in Obama's administration as part of an overhaul of the healthcare system.
