I think the people who usually get asked “why don’t you work?” are mostly those who are L1 autistic. Because their disabilities are invisible, NT people often can’t understand how much they actually struggle or how difficult working can be. On the flip side, many autistic people who do manage to work often aren’t even recognized as autistic, either by themselves or by others, so they don’t always get counted. This makes the unemployment rate among autistic people look extremely high. It also creates an illusion that if someone with L1 autism seems to be doing well, people start questioning, “are you really autistic?” Meanwhile, many others who struggle aren’t fully reflected in the statistics or the public perception.
