Medicare is the federal health care program for senior citizens. Relied upon by millions and millions of older Americans, the program is popular but facing some troubling issues. As health care costs continue to rise, so do Medicare costs. Also, as baby boomers retire, they are creating a generational bulge, pushing the system to the breaking point. That point will come within the next decade, when Medicare will become insolvent. The long-term view for the program does not improve. There are tens of trillions of dollars in unfunded liabilities, meaning the program will not have the funds to provide care for the retiring generations to come.
