How is Seabiscuit a symbol of America and its people?

During the Great Depression, the American people needed a hero, and they found one in Seabiscuit. The little horse was, in many ways, what Americans believed was best about themselves. He was not much to look at, came from an uninspiring background, and on the surface he didn't have much about him that predicted that he would be a winner. But through a combination of intelligence, courage, heart, and hard work the little horse broke record after record. Even what was ordinarily considered a career-ending injury didn't stop him: he returned from retirement to win the biggest and most prestigious race of the era. The American people identified strongly with Seabiscuit, and considered his story a very inspiring one for themselves.
