I’ll weigh in here… I agree with comments suggesting that the ridiculously high drinking age contributes to binge drinking rather than moderate social drinking.
Also, I keep reading about drinks being drugged with date rape pills, and I never read about that in decades past when I went to college, so I think the prevalence of that risk is absolutely new.
Also, when there was no Internet, teens and young adults had few sources of nude photos, and now they can watch countless people having sex online if they want to, and get addicted to porn, affecting their views toward intimacy and the people around them, and affecting their desires and expectations for what they want out of an encounter. This is reinforced by certain lyrics and music videos, computer games, TV shows, etc. – on a massive scale that dwarfs any outside influence young people faced a few decades ago.
Let’s add that the age of marriage keeps going up and up every decade, with many only living together now and not marrying at all, and that is in part a reflection of the lack of “dating” culture in the sense of dating that leads to long-term relationships and marriage – much of it has been replaced with one-night stands and friends with benefits relationships, heavy on the sex and light on the love and romance.
I could go on, but I think things have changed entirely in the past 35 years making fraternities wilder and more dangerous, especially for females who go to their parties. Once upon a time fraternities might have fostered socializing that led to marriages, and now they seem to foster socializing that leads to rape of unconscious drugged sorority girls – sometimes filmed as someone mentioned – and other atrocities, including addictions and overdoses.
