I think Arnold´s Disabilities are no problem for him to get rich and famous. Many people who are rich and famous have disabilities for example Steven Hawking. But some people have preconception so they wouldn´t accept some rich and famous guy with disabilities.      Also he probably would get bullied in the public by haters who don´t grant him the glory and the achievments. So all in all I think he could get famous but with some restrictions. And I would definitely grant him his famous.
