Examples of social inequality in To Kill a Mockingbird?

Many of the characters in Harper Lee's To Kill a
Mockingbird suffer from various forms of social bias. Certainly, Boo Radley
is a prime example. His mental instability is dealt with by shutting him away in the
family home, and he is blamed for any abnormality that occurs in the town. All of
Maycomb's African-American population face racial biases of some sort, and Tom Robinson
faces harsher treatment because of his supposed connection with the white Mayella Ewell.
Dolphus Raymond, who prefers the company of African-Americans, is considered mentally
unstable because of this decision. The poor citizens of Maycomb face different
inequities. The Cunningham and Ewell families, though dirt poor, are treated
differently; the Cunninghams are poor but honest, while the Ewells are considered
"trash." Women also face unequal status in Depression era Alabama. They are not allowed
to participate on juries, few of them are employed, and most of them are presented in a
quirky view by the author.
