We need to pare back on the big three of Social Security, Medicare, and Medicaid. Implementing a gradual rise in the eligibility age of Social Security and Medicare to age 70 for both would be a start. (Or if we do keep Medicare eligibility at age 65, increase the premiums for those under age 70.)
That's ridiculous. If you make old people work another five years, it becomes that much harder for younger people to find jobs.
Then we either have to raise taxes or reduce the monthly and medical benefits as the current system is not sustainable. Which is your preference?
