For over a decade now, Gallup has polled Americans on their satisfaction with health-care costs. They've recently noticed a gap between satisfaction of the privately insured and those with Medicare or Medicaid, which widened in the most recent round of research:
In some ways this is pretty intuitive. Medicaid and Medicare are limited in their ability to raise the cost of benefits, whereas private insurers have no such brake pedal. Gallup's Jeffrey M. Jones writes that a lot of this appears to be driven by the growing cost of private insurance in recent years, as the cost of public programs have remained relatively stable for patients (if not for the government):
The changing landscape of health insurance in recent decades could be affecting privately insured Americans' satisfaction with their health costs. The vast majority (64%) of Americans with private insurance now say their health premiums costs are shared. This is up from 54% in 2001. While the 22% saying they personally pay the entire cost has not changed appreciably, the 10% saying their employer pays the entire cost is down by more than half from 2001.
