If you construct a society with no sense in it, you can't be surprised if people behave destructively and irrationally. And if you set an example of violent greed, you can't be surprised if people follow it.
David Cameron was involved in a shop-window-breaking incident in Oxford while a member of the Bullingdon Club. "Just youthful exuberance", of course. He didn't spend any nights in prison.
And if bankers and company directors grab millions in pay and pension rights, you can't be surprised if ordinary kids try to grab what they want.
What "utterly unacceptable, criminal behaviour" actually means is: "tug your forelocks and respect our property as we exploit society to our own advantage". And "We'll throw your parents out of their homes if you don't behave," merely compounds the nonsense.
