Yea, there is discrimination occurring and it won't go away anytime soon. My sister lost her job after training her youthful replacement about five years ago. She considered fighting it but at 62 she could work part time and collect on her deceased husbands SS until she turned 65. She found that although he had died in the early 70's, his SS check was a bit more than hers. She'll continue taking his check until 70 when her's max's out and she'll be fine. We, as a family, help her when she needs it as it should be.
Play the game if you can! We've all paid into the system that was designed to make sure we were somewhat secure in our older years. Though I may never retire, I (or my wife) will get back every fuggin cent I paid into the system!
