I think the degredation of today's youth is centered around 4 main points. Capitalism (materialism), a culture of individualism (pop culture), a liberal news media, and culture with respect to geographic location.
IMO my generation has lost touch with a true sense of patriotism, instead focusing on popular culture. They are much more worried about wearing the most fad clothing, buying that new iphone, and partying it up with their friends than Iraq or our military. Their parents, locked in busy and stressful environments of their own, only police them to some extent. They are very much concentrated on materialism, wealth, and image. These kids are "on their own program" so to speak. That being said, you're going to see a much different attitude here in SoCal compared to say, Charleston South Carolina. In SC, you're probably more liable to find people much more patriotic and supportive. So, in short, it depends on which part of the country you're in. If you're in the south or midwest vs. northeast or pacific coast.
The news media has done a wonderful job of emphasizing every negative aspect of this war. I'm not going to stand up and say that everything has gone perfectly, but I do understand what is happening NOW. If the average citizen doesn't go beyond their daily news casts to become informed, they will become the opposite of that... misinformed. This permeates into today's youth as well.
My overall opinion is that this new culture is of "not caring" ... focusing on partying, making money, and looking good while doing it. Honestly, I wanted to freakin' choke many of the students I shared classrooms with. My overall feeling in my last year of college was that nobody cared. Nobody talked about it, and if they did it put a heavy negative undertone on today's military.
