Because it's not about the money, it's about the conflict between the characters. Despite them talking about a real-world company, this still concerns the characters that the wrestlers are portraying. Professional wrestling is by and large a scripted drama series about athletes, with scenes of interpersonal conflicts connected with stuntwork scenes of simulated competition. What you're calling out is a plot point, even if it blurs lines with the real world. It's a storytelling property that modern wrestling employs, if not uniquely then distinctly; because the promotion knows that modern fans regularly argue over which wrestlers are most valuable to the promotion, the promotions use that to add heat to the character drama.
