This generation is always assuming that, in a crowd, the people there aren't really people with lives and feelings. But some people do realize that, and the artist is asking whether or not you actually see that when they do.
This is probably referring to the fact that people wish on shooting stars, and that those wishes come true. They are saying that they want to wish for something.
This artist is saying that this person always belittles him/herself. Thinking that everyone else deserves good lives, and they don't. Even though every person deserves equal rights.
