What key events, post WWII, have led to a cultural collapse in the United States?

by Jaalix

Many people I've spoken about this topic with seem to agree that the United States of America has suffered a great social decline in the past 50 years or so. This isn't about "glory days", we are genuinely intrigued as to where the sense of personal responsibility and community have gone to and what modern historical events have played part in this? Please help educate myself and my friends on what catalysts spurred our current social decline.

Hi OP, This question may be a better fit for /r/AskSocialScience (check with the mods over there). Meanwhile, just a reminder that this sub does not permit discussion of current affairs, which we've defined as anything within the last 20 years. So your question about "the past 50 years" may not be addressable here, or at least not to the degree you'd like.

Lastly, since this question may be politically loaded, a reminder to potential respondents: Please review subreddit rules for answers before responding. In brief, provide in-depth analysis based on solid -- preferably cited -- source material. No current events, opinion, soapboxing, arguing with the OP, anecdotes, speculation, or link-dropping. Thanks all!
