Yes, and Texas teachers often take early retirement after they’ve put in the requisite number of years, then get another job that pays into the SS system so they get checks from both systems.
Double-dipping, kinda like military retirees do.
I am retired military and on social security. Yep I'm one of those dirty blankity blank double dippers. I'm doing so well on the slightly more than 2000 a month that I'm living high on the hog.....wait... this hog is dead... been dead............. a long time.
