Yesterday while zapping the TV shows I've observed what the true purpose of all the political talk shows and talk show hosts is: they are the modern day circus presided by a modern day jester.
For you see, the jester has a very important role: it diffuses the public negativity.
As a ruler or ruling party that also does questionable social or economical decisions you don't really want people on the streets. You don't want resentment to grow within people. So - the jester is actually something you need. Of course, they may sting a little but remember: sticks and stones...
