What exactly is the big deal about raising the retirement age?

First of all, I really do not believe for one second that I will ever see a cent of the money I have already put into Social Security or Medicare. So I admit that my question is mildly disingenuous.

But having said it, there are gradually increasing takers of the benefit, and gradually fewer payers of the benefit. And there are not enough rich people or riches to tax to cover the cost forever. So something should be done about SS and Medicaire.

One solution to extend the retirement age. It would probably only affect those younger than 55, and for most people it would be moment decades away. It would buy a few more years , and give me a chance to get some of my money back.

Great idea in my opinion. But I have noticed that when the topic comes up, people gripe vigorously. And often enough it is people old enough that the change would not affect them anyway.

What is so sacred about age 66. What is so awful about age 69? What is the big objection?
