One way they're cracking down now is kicking fraternities off campus - and the fraternities apparently aren't wising up very well to reverse the trend, at least not nationwide. In the last two weeks two young men have died in hazing events that included alcohol at other schools.
Deaths directly attributed to Alcohol abuse just didn't seem to be a thing back in the day, or maybe they just weren't reported. I don't think kids had the disposable income back in the 60's and 70's that they do now, and getting trashed every night just didn't happen. Yes, there was plenty of drinking, but pot and other drugs became more popular around 1970 and at many parties people were doing drugs rather than Jell-O shots.
Historic watering holes were of course Kens, the Keg, and then the Electric Eye. With the drinking age at 21 and pretty strict enforcement we just didn't do a bunch of bar stuff. Plus the fraternities could all serve booze in their houses.
