Why was "circus" never rated, by it's quality. Why were they all lumped together, under the banner of "Circus!!!"

The above video was sent to me by a friend and loyal supporter of the circus as a shining example of a way to do an interview. I strongly disagree. It is a shameful way to do an interview, when presented with video's like this one below, which was on the same link. Why did we not self regulate as other animal industries have done? Why did we not get the bad out, regardless of the family ties, or history we may have had with them. Why did we not have to courage to expose the bandit's, and eliminate the amateurs? If show's had been rated "The good, the bad, and the ugly" guess where the public would be spending their few entertainment dollars, and guess who would not now be trying to justify or explain away what the people have seen. I think, a lot less of the "self promotion" which we now see, and instead concentrate on "industry promotion" by exposing trash ourselves will go a long way in possibly turning this thing around.
