The problem is that the Social Security system needs to be fixed, to make sure it remains solvent.
One way to fix it is to increase the retirement age, but that will make the problem worse. Wealthier Americans will not be affected as much as many poorer Americans who will not live to see any benefits. This will effectively make their payments into the system, a tax on them for the benefit of the wealthy.
Another solution is through means-testing Social Security, but the program was designed without means-testing to make it more difficult to cut later on.
