Didn't quite get the bit about growing up and paying your debts - does it mean the parents?I need to watch again. I was hoping it was going to say " but one day we will grow up and then you won't see us for dust!"( or something like that).
I thought that was a little odd, too, and a bit unnecessary. I felt like the angry tone at the end really detracted from the message. It's quite interesting how many images there are of the kids being in trouble and being shamed once they spliced all the videos together. Quite sad, really.
