There's the feel-good story, and then there's the harsh reality. The reality is, SSDI enrollment has gone up by a factor of 3X since this "welfare reform" thing passed.
I have a neighbor who is reasonably fit (he can move 100lb+ stones in his side gig as a landscaper), but he is on SSDI and collects a cool $3K/mo for doing nothing. Once you are on SSDI, it's very difficult to kick you off.
