Rich: 'nothin silly about it. You just need to bone up on your American History.
Disillusionment is markedly different that having a different political agenda (the cause of the whig, tory, black horse, democratic, republican, libertarian, etc. parties) and basic disagreement over economics and social policy. Disillusionment means to be stripped of your ideals and made bitter. Prior to the late 60s and early 70s (Vietnam, Watergate, etc.) the nation had a certain innocence and still held ideals: even the young people. Compare the reverence the older generations held for FDR, Truman & Kennedy with the reverence held for Nixon, Johnson & Carter. This time period, for the first time since the Civil War, millions of Americans started to feel threatened by the government and the ideal of Democracy: the whole vision the founding fathers worked so hard to solidify. I meet very few people who can honestly say or feel they hold the slightist bit of political efficacy. This is disillusionment, my friend, and it it getting worse.
Drugs have been around, you say! Well I can’t argue with that! What I can say is that synthetic, available, recreational drugs have NOT been around for centuries. Big difference when it comes to pervasiveness in American culture.
Anarchy, or getting rid of any centralized government, really hit it’s violent stride in the late 70s. Just because all western nations have governments, doesn’t mean that the anarchist movement isn’t stronger than ever.
Free love used to be able to be cured (for the most part) with a bit of the old antibiotics, now you run the risk of AIDS. There are nations on this earth where the rate of AIDS is 25% or more of the general population.
I’d like to ramble on, but I’ve got band practice now - the guys are showing up any minute. What I’m saying is that these factors most definitely are contributing to the changing attitudes in music and art. If you disagree with me, it is you who are just plain goofy. 
Hell is Other People.
