Except for states (mostly in the South) that refused to accept Medicaid expansion under the Affordable Care Act, the ACA has been a boon for "safety-net'' hospitals that service large numbers of poor people. That's because the ACA, by enabling millions of previously uninsured people to get insurance (many of them via Medicaid programs), has dramatically reduced pressure on hospitals to provide uncompensated care.
