Sometimes, people would rather see themselves as
lazy or
free spirits than admit to disability. I was acquainted for a time with a homeless man who seemed able bodied but had a mental health issue. He quit his job and walked away from his worldly possessions to get off the zombifying drugs required to make him employable. I have a different disability but made similar choices, so I am sympathetic. But he was very resistant to admitting that he was too handicapped to hold down a job. I knew him a while before that became clear to me. And it isn't anything you would infer at first glance. If you saw him, he looked tall and strong and able bodied, he sounds intelligent and is intelligent and the degree to which he is not mentally sound is just not obvious to casual inspection.
I have two adult sons who have never had jobs. They also look hail and hardy. They both have some issues. We are still trying to work out how they can make money in spite of being basically unemployable.
I suspect this happens more than is recognized. My handicap was not identified until age 35. I got called "lazy" a lot until I had a diagnosis. I am a woman and was fortunate to be able to hide out for many years behind the title of full time wife and mom.
