There probably is an easy formula. Sadly, SS and Medicare is a useful political football. It's a disgusting and evil way that politicians use the elderly in America.
Some of these 'fixes' are already in, including paying more in and raising retirement age.
Social Security Disability is a criminal scam. The intended recipients take a back seat to the criminals. Huge amounts of money paid out to scammers. Yes, take a hatchet to it, and prosecute the abusers inside and out.
I don't see the same issues with Medicare unless combined with the Disability scams. Get rid of the Disability scams and their health payments go away too.
Become the kind of person that when your feet hit the floor in the morning, Satan groans and says, "OH NO, HE'S AWAKE".
