In the early 1960's, about 30% of seniors lived in poverty. The combination of Social Security and Medicare cut by more than half the seniors' poverty rate.
Today 56% of Americans have savings of less than $25,000. Median-income families are straining to pay to fill gas tanks and tuition bills.
Turning medicare into a voucher that year by year becomes more and more inadequate to pay the cost of insuring someone over 65 years of age is a guaranteed recipe for going back 50 years, prior to Medicare, when nearly one out of three seniors were poor.
Sometimes reform ideas are dangerous junk.
