Only “responsible” 21-year-olds should be allowed to purchase and drink alcohol. I was a high school teacher in Minnesota during the late 1970s when Minnesota lawmakers lowered the legal drinking age to 18. This new freedom went straight to their heads.
Serious problems occurred in our school because many of the seniors were 18. They took advantage of the new law and drank alcoholic beverages during school from their cars, from lockers, and from stashes.
Additionally, this made alcohol easily available to underclassmates. This was “cool” for the students but resulted in severe penalties such as suspensions and loss of eligibility for school activities. Apparently the students developed a false sense of “adulthood” that emboldened them to do irrational things that were dangerous.
Within two years, the legal age was raised to 19 and, shortly after, the legal drinking age was returned to 21.
We must acknowledge that underage drinking is a serious problem throughout all public and private schools, both on and off campus. Some university presidents seem to only want “experienced” drinkers on their campuses.
