Steampunk without commentary on the exploitative machinations of imperialism is not steampunk.Cyberpunk without commentary on capitalism's efforts to buy the world out from under us is not cyberpunk.
Solarpunk without commentary on how to grow a brighter future for everyone instead of submitting to gloom is not solarpunk.
These three make a trifecta of how capitalism took over, what can happen if it continues, and how to prevent it from doing so. What was, is, and still could be.
