Why doesn't WWE just run with real life angles?

[The One]

I mean, Hardy/Edge was so massive that Edge still is enjoying being one of the top players in the business directly because of how real life effected his heel heat. Why not run with stuff like this more often. Someone just suggested that Triple H come back as a sledgehammer wielding bad ass who talks about how he's banging the boss' daughter and he can do whatever he wants. That would be a kind of new and refreshing reprise of the McMahon/Helmsley Era. If someone gets injured, just go ahead and say they're injured. You can run a ton of those real dangers of wrestling ads or whatever. I mean I'm not suggesting they turn the entire show into a worked shoot, but sometimes the real life people do a better job of being interesting characters than the characters themselves.
