In The Lesson by Toni Cade Bambara, what is the lesson Miss Moore is trying to teach the children?

Miss Moore is a college-educated woman who has come to live in a poor, African-American neighborhood of New York. She takes upon herself the responsibility to teach the neighborhood children about the larger community and the problems that African Americans and poor people face in the world. She takes the neighborhood children on field trips and exposes them to various issues and ways of life. She challenges the children to think about what they see—like the prices on the toys in F. A. O. Schwarz—to question the status quo, and to find out more about the world around them. Miss Moore also imparts her belief in the need for the poor people to step up and demand their fair share of America's wealth.
