Music is powerful for the young, for sure, but it was the drugs which really ruined the nation. Drugs do two things..They embolden the user through the loss of inhibition. That causes him/her to do things they would never do otherwise. This is a result of the drug effect on the frontal lobes of the brain which houses judgment. If you turn millions of people like that loose on your society, they will wreak havoc and that is what we had and what we have in America today, in spades. Drug use and addiction is the elephant in the room and people do not consider the damage it does because so many are users themselves and do not want it discussed. Look at the support now for legalization of marijuana? If you can't control it, legalize it. Political correctness is the other driving issue. Social pressures are the unwritten laws which govern civilized society and give power to majority opinion. There is no fraud because people can say how they feel about right and wrong. Political correctness forces a false morality on a society which cannot last because it is totally unnatural. It is soft tyranny and is very destructive on all the functions of society. At this point, with open borders, I think the American haters may have won..Their secret weapon..A state run media just like them, the usurpers of freedom.
You are right on all counts. But, I think music was a strong contributor to the advance of drugs and cultural shift that may have not happened or been slowed to glacier speed had we still been listening to the Four Seasons, Chubby Checker and Leslie Gore.
