Here is the reality in a nutshell.
Medicare is bankrupting the country because it doesn't collect enough in premiums to cover the benefits paid out. Now our government is mandating that private insurance pay out more benefits. In order to stay more solvent than Medicare, the premiums will have to increase at the same rate as the benefits paid.
One way to save Medicare is to increase the premiums to cover the benefits paid, (what a wild and crazy concept to take in more than you pay out) and then Medicare premiums would be just as high as private insurance.
