Was it a good idea to keep going to the trash mountains? I think it was, (at least for now) this is because they can still earn money if they collected trash and while they were doing that, Rukku could make necklaces that they could sell at the end of the day. According to the text when Arule said that if they stopped giving the trash guy trash, he could lower their prices if they ever came back. I think the time they should stop working for the trash guy is when they can start buying their own beads and rope and can make necklaces Their as thier main source of income.
