What does Esperanza think is wrong with the barrio?

Esperanza wants a nice suburban house with a garden, like the ones where her father works. On the weekends, the family visits these houses and dreams about moving there. Esperanza has stopped going with her family. She, too, would like to live in one of those houses, but she is tired of looking at what she cannot have. She imagines that when she owns one of these houses in the future, she will not forget where she is from. When bums pass her house she will invite them in and give them a place to live in her attic, because she knows, she says, “how it is to be without a house.” When people think that the squeaking in the attic is rats, she will shake her head and say it is bums.
