An overall goal of current disability-rights legislation is normalization.
This is so true because people with some kind of disability want to live a normal life, which means having equal job opportunities, or entertainment opportunities as any other individual. That is why the US legislation helps disabled people to have jobs, and be treated fairly, with the proper infrastructure condition to help them to live a normal life. For instance, proper facilities in public buildings, in public parks or public transportation.
