What the hell is all this talk about someone "deserving" a title?
Wrestling 101 here, which it seems a lot of folks in this thread skipped: The man who deserves the title is the man who puts asses in seats. Over the past couple of years, this has been warped slightly, into "the man we believe could put asses into seats", due in no small part to the youth movement. You gotta get 'em over somehow, and Cena/Orton/Edge can only carry so many people on their own. A championship might be a prop, but it isn't something you give to a guy like some "Employee of the Month" award. Someone might "deserve" a bigger paycheck, or a bigger merchandising cut, but no one "deserves" championships. Those are earned by a proven ability to make money for your company.
Another big myth- Christian isn't a WWE champion, just because he was a TNA champion, because Vince says blah blah....... and so forth. The WWE is a multinational multimedia company. The days of them doing things on a whim, because it might be a good idea are
gone. These days, everything is market researched and focus tested into sterility.
Christian doesn't draw. It's hard for the Peep Marks around here to get, but people that are passionate about Christian are in the minority. The fan base is younger and less informed. The TLC matches he was in are a distant memory; they know little, if anything about Christian's NWA title run, much less that there's such a thing as the NWA (be it the National Wrestling Alliance or *****s With Attitude. Kids these days.

)
Look, Christian is 37. There are people that are older then him wrestling and winning championships, yes. But they were made long before their late 30's. The WWE simply isn't creating new champions out of people Christian's age. It's not worth the time investment for them, when they could be using those prime segments to push people like Barrett, Sheamus, Swagger, Punk, or several other people, in the hopes that one of them breaks through and gives the WWE several successful years.
Sorry, Peep Show. If Christian was going to be a world champion (of a real championship), it would have happened by now.
