That's theoretical, NOT practical. The issue is WHICH job. We are all inclined towards some job, but that's not necessarily the job or pay that we want.
I think you're touching on disability often being about an interaction between the individual's deviation from normal and environment. Take the bright young autistic engineer who can't get past his first month. However, if there was a company that was more understanding or hired a coach, or put the autistic engineer in the basement to work, his disability might go away.
Take myself for an example, I have ADHD and dysgraphia. I did really bad in school until I went to college and could type everything and structure my life in a such a manner to minimize my challenges. That's why I struggle with this stuff, because context matters and I don't think there will ever be a one size fits all approach.
But working as a psychologist who specializes in neurodevelopmental disorders has me worried about a few things regarding disability:
(1) The welfare state incentivizes more people to leach off the system (I get more if I have x diagnoses). I think it's a pretty well understood fact that when Clinton changed welfare policies and unemployment, the same people just went out and got disability benefits instead of developing their skills.
(2) The covid era has been a great example of showing that many people would rather sit on their asses for 600 dollars a week and consume over contribute. There are tons of job shortages for jobs that are not as financially reinforcing or rewarding. I get it though.
(3) It drives me crazy because most of the people that I've work with who have a mild to moderate ID love their "jobs" or volunteer positions and would work more if they couldn't lose their benefits.
(4) Disability is kind of like porn... You know it when you see it.
(5) Work and not having a safety net is important for growth. I've got a brother who was at a real risk of becoming a neckbeard/neet. My parents even bought him a trailer to live in when he was 20. However, when my parents started pulling their financial support away after he dropped out college, that brother got a job, lost 100 pounds, and became a cop (his dream). Although "uncomfortable," having the "safety net" pulled out from the brother really helped him develop and grow. He could have easily went the other way, into disability land when he injured his back for not tazering someone. Now he's a court investigator and has two great kids and a wonderful wife. That same brother also had his colon removed and poops in a bag. But, he's out there contributing.
(6) People have every right to mess their lives up and not be the best they could be. But, I think that's more an induvial issue than a societal one.
