The original Digimon is about the death of imagination and childhood innocence in a capitalist system. Before the jump into the digiverse, they live in 90s Japan (Tokyo maybe?), it's all grey tones, and every one of the children's parents is distant, many of them because of issues of capitalism. The Digiverse provides a literal escape from 90s capitalist Japan, but also a mental escape from the monotony of growing up to reproduce capitalism. No I will not elaborate, and Wizardmon goes hard.
