This is really interesting to read and reflect on. Honestly, I'm not sure these values are particular to Pixar, so much as they are an "America in general" thing.
Also, this was striking:
Although he causes all this, and at no small cost to his daughter’s mental health, Riley’s dad is not depicted as a villain. He loves his family, they love him, and together they work through the deprivations caused by the move. The narrative does nothing to condemn this state of affairs; indeed, it is Riley’s burden to accept them.
I don't think the fact that the move is treated as Riley's burden is all about capitalism per se; it's about the fact that adults in our culture don't generally take children's interests into account, or consider their problems important. It's always "they'll get over it," even when something is making a child very unhappy.
