High healthcare costs taking toll on Massachusetts insured

Despite Massachusetts' 2006 health insurance overhaul, healthcare costs are devouring more than 10% of thousands of residents' income, according to a new study from Families USA, a nonprofit organization that lobbies for affordable care. The study found that more than 1 million Massachusetts residents are in families that will spend more than 10% of their pretax income on healthcare this year, even though the vast majority of them have health insurance.
