How important is an unbeaten record these days?

Considering, most of these boxers with unbeaten records past 20-25 fights have been spoon-fed palooka's, had the ref on their side in every fight and been the beneficiary of at least one gift decision. Why is it so scary a prospect for the 0 to go? Everyone who ever lived has suffered losses in one way or another and it really is what makes you a stronger person, how you deal with it. Look at Lady GaGa as a prime example. She was manufactured, hyped, spoon-fed to the mindless mainstream music fans, every single person on the planet had their eardrums violated by her music one way or another. Now she is left to fend for herself and she has all but vanished from existence. Two years ago she was on a similar pedestal to Floyd Mayweather, Jr. Now the veil has been lifted and she is just another Rod Salka. Think about boxers like Carlos Molina, Erislandy Lara and Gabriel Campillo. Realistically fighters like this must go into the bigger fights knowing that they are most likely to pick up the "L" regardless of how convincingly they expose the house fighter. They don't really have a choice but to depend on the fans judgement and perception of justice/reality. Is it just going to get worse from here? Will we ever have an era again where the best fight the best and everyone wins some and loses some without controversy? How much importance do you yourself put on a fighter being unbeaten? Is it something we demand as an audience? Or is it more for the casual viewer?
