RWBY is an anime that has inferiority complexes, and since it's about warriors fighting for humanity, this is more important. Even the weak want to fight. The strong want to win. Everyone wants to live happily ever after.
This little girl is more determined than the others in most areas. She isn't driven by pay or pleasure, but by a wanting need to defend others. Quotes like this are what lead you to believe that she is a solemn serious girl (she's totally not)
Like few anime, RWBY has racism, or speciesism, that is really the cause of over half of this world's troubles. A simple want to be able to walk down the street lead to a terrorist group that could easily have never started.

Of course, this show is actually pretty funny. This socially awkward Ruby describes me so well <3
