Social Security is incredibly complicated. There’s a canonical answer to every question. Someone like Elon doesn’t know or care about the details.

There’s also a number of programs. SSI, Disabilty, Death Benefits, retirement, etc. Blind people are eligible for a benefit by law.

Is there, somewhere in the United States, a disabled, blind child whose parents are deceased and whose birthdate is unknown? Almost certainly yes.

Is that fraud? Only if you’re a “genius” who targets victims who can’t fight back to demonstrate his intellect.
