Ecclesiastes 1:10 says "Is there a thing of which it is said, "See, this is new"? It has been already in the ages before us." Between that and "Do not say, “Why were the former days better than these?” For you do not inquire wisely concerning this." (7:10 ) I would have to conclude that politics has always been corrupt and things are not worse now than things were in previous years. It is now just easier to see what is going on in spite of the media bias.
