Actually all higher primates do capitalism. Bonobos pay with food for sex, Chipanzees pay with support for a higher rank, Orangs pay with food for other orangs making them a bad out of leaves. I suggest to read Barterverse: Galactic Economics 1: Happy Existence
Orangs do that. One Orang is collecting food and giving to to another Orang building a bed from leaves.
Why? Because the first Orang is better at collecting food and the second at building beds.
