71, retired in 1988.
But even with that, a smaller COLA is still an increase, and is not actually a cut. The way I understand a cut is, if I'm getting $100 regularly, a cut would mean I get less than $100. And since this is not true, I think the DUmmy's outrage is unwarranted, and his thread title incorrect.
As to the semantics, you are correct. However, looking at it through the eyes of a recently retired member of the armed services, during your 20+ years of service you were repeatedly assured you would receive a retainer (actual terminology in the law) that will be adjusted for inflation. Shortly after you leave active duty Congress announces they are going to renege on that promise. If in 2015 active and retired (over 62) military, SSI, government employees etc. etc. all receive a 1.5% cola but you receive a .5% cola wouldn't you be a bit disappointed?
