You misspelled “stupidity.”
During the seventies and eighties the Federal court system forced the majority of long term mental health care facilities to be shut down. Where do you think people who used to be cared for in that way are now? Some are homeless, some just died, and others are on the dole.
No doubt some are better off, but for many it would be better for them to be in care facilities because some of them have mental issues that need not be permanent if they get more intensive treatment for a time.
Not that there isn’t fraud, but fraud is neither the whole story nor even the biggest part of it.
I had a family member who lived on disability because of mental illness. It was plenty real. He couldn’t take care of himself when things got bad and didn’t survive until the age of 30. He was a sweetheart.
