Public schools are essential to make the American dream work, but schools are also the arena in which many Americans first fail. Failure there almost cer-tainly guarantees failure from then on. In the dream, failure results from lack of individual merit and effort; in reality, failure in school too closely tracks structures of racial and class inequality. Schools too often reinforce rather than contend against the intergenerational paradox at the heart of the American dream. That is understandable but not acceptable.
I think the paragrph emphasizes how important public schools are to the American Dream and how they may help or harm it. Even though the dream says that failure is due to personal effort and merit, the truth is that schools often reflect and support structural racial and class inequality. Standardized tests, which are a big part of success, can hurt kids from poor backgrounds. Class and race working together in schools is a big problem that makes it harder for everyone to reach their goals. For example, differences in school funding and opportunities would strengthen the case and show how important it is to fix systemic problems right away to close the gap between the dream and its reality.
