The real problem is SSDI. Way too many people on SSDI are out waterskiing on the weekends. If you can walk, stand, or sit on your own, NO disability!
Medicaid and Medicare are bigger cost items than SSDI but you are right it is a huge problem and I’d bet 80% fraud.
While I agree that there are to many scammers, I can’t wait for a debilitating injury, or disease to strike you and have others speak your words back at you while laughing.
