In medical news, a new study by Consumer Reports has found that 16 percent of the U.S. population has no health insurance and that another 24 percent of Americans are living with skeletal health insurance that barely covers their medical needs and leaves them unprepared to pay for major medical expenses. Overall, 49 percent of Americans surveyed said they were “somewhat” to “completely” unprepared to cope with a costly medical emergency over the coming year. The Consumer Reports investigation notes that the nation’s six biggest private health insurers collectively earned nearly $11 billion in profits last year.
