When the company my father worked for downsized, he was demoted to a lower paying position. Having worked for the same company for about 30 years, he was not happy to say the least. He was nearing 62 at the time this happened, so he ended up working a few more months and then taking early retirement.
He wasn't able to get the maximum social security benefits, but with his retirement and the partial social security he was able to retire and not worry. In fact he was collecting almost as much as he would have made if he had continued to work until he was 65 because when he was demoted he lost a large part of his salary.
I know people are living longer, but I don't like the idea of the full retirement age continuing to change. Some people are not living longer and some people are unable to work much beyond the age of 65 if that long.
