It is a popular myth that society is especially corrupt today, if you look at it logically, this is the way it has always been. In truth, the world is probably better than it has ever been. More people are living life the way they want to than ever before.
Throughout the ages people have lamented that the world is full of sin. In the olden days people were ripped to pieces for public entertainment, prisoners fed to dogs, crucified, boiled in oil even. The bible even mentions bestiality, incest and countless other repugnant sins. So what moral high ground are people speaking of? In this context, kissing videos are not some calamity upon the world. You can stop your child watching youtube and tv or stop them using the internet altogether.
And moral decay is not the reason for the decline of empires, it is arrogance and overreach. Aurangzeb, was a most pious ruler but his ambition and constant warring set off the death knell for the Mughal empire.
Actually that sounds exactly the opposite of 'control'.
