It's not a religion, because it is not based on faith. It consistently delivers results whether its practitioners believe in it or not.
Capitalism solves things with a good enough neural net. Socialism says that it can solve problems analytically, but it just uses a smaller inferior neural net of centralized bureaucracy with access to less data, and a slower learning rate.
This is also why corporations don't grow without limit - they become constricted by bureaucracy and unable to adapt, and smaller, nimbler outfits pick them off.
