The Mentally and Physically Disabled
Mentally and physically disabled people because they are in fact disabled, either cannot speak for themselves, or no one listens to what they have to say because they’re disabled. So in the real world they indeed need someone who is accepted and respected in societies help advocating for them. People such as siblings, parents or grandparents
Relations
Slaves, like Jim from the book used to be denied the rights to education, housing, and any employment other than being a slave, because of their skin color. The mentally and physically disabled are also denied the rights to education, housing, and employment because of their incompetence. These relate to each other because in both cases, the people are being denied rights due to something they were born with and cannot change.
