Honest question… what changed in the 60’s?

[LetsFNgo]

So while at Carlisle Friday I found a bunch of car magazines and ended up picking up about 30 late 50’s- early 70’s Hot Rods and PHR’s.

In the January 1963 Hot Rod is an ad, paid for by George Hurst but not selling any product. Just talking about how young men are the future and how we need “…other active, free thinking young Americans like him…”

What changed over that decade and the decades since? I was born in 1990, and just reading this today makes me both proud and sad. Proud that a country held its young men in such high regard, and sad that I wonder when it all changed. I know the 60’s changed a lot from the beginning to the end, and maybe Vietnam played a large part of that. But I’d love to hear other opinions about that decade and where it all changed.
