The 26 states that have rejected the Medicaid expansion are home to about half of the country’s population, but about 68 percent of poor, uninsured blacks and single mothers. About 60 percent of the country’s uninsured working poor are in those states. Among those excluded are about 435,000 cashiers, 341,000 cooks and 253,000 nurses’ aides.
“The irony is that these states that are rejecting Medicaid expansion — many of them Southern — are the very places where the concentration of poverty and lack of health insurance are the most acute,” said Dr. H. Jack Geiger, a founder of the community health center model. “It is their populations that have the highest burden of illness and costs to the entire health care system.”
It isn't ironical--these states don't want to pay for it.
Tens of millions more won't be able to be insured anyway thanks to the "exchanges" being outrageously expensive and laughably inferior to company-paid plans, plans that are likely to be a thing of the past when corporations get done with strongarming Congress to put in loopholes. Right now companies with 50 or more employees HAVE to provide health insurance, but you know that will change.
