Answer:
The West Side Story is a musical that was first performed in 1957, so a lot has changed in terms of race relations and gang behaviors since then. In general, race relations have improved significantly over the past several decades, though there is still a long way to go. Many laws and policies that were designed to discriminate against people of color have been overturned, and there has been a greater focus on promoting equality and understanding between different racial and ethnic groups.
As for gang behaviors, these have also changed significantly over the years. Gangs have been a part of many urban communities for a long time, and they often reflect the social and economic conditions in which they exist. In recent years, there has been a focus on preventing young people from joining gangs and on addressing the root causes of gang involvement. This has included efforts to provide education, job training, and other support services to at-risk youth, as well as efforts to strengthen community bonds and reduce the isolation that can fuel gang involvement.
