Hopper's Speech.
You let one ant stand up to us, then they all might stand up. Those puny little ants outnumber us a hundred to one. And if they ever figure that out, there goes our way of life! It's not about food. It's about keeping those ants in line. That's why we're going back! Does anybody else wanna stay?
~ Hopper: A Bug's Life
A Bug's Life is a wonderful movie with a message of radical hope. Those with power and wealth mainly have so through exploiting and controlling others.
Ants are not meant to serve grasshoppers. I've seen these ants do great things, and year after year, they somehow manage to pick enough food for themselves and you. So-so who's the weaker species? Ants don't serve grasshoppers! It's you who need us! We're a lot stronger than you say we are. And you know it, don't you?
~ Flik: A Bug's Life
But all it takes is one person to stand up and say, "No!"
