Those young women were all 21 or older. Did they have fully developed decision making ability? Nope. But they were adults, and it's silly to state Cline should have been following them around supervising their behavior.
Your wealth envy is showing.
No wealth envy just parenting! My youngest son is 21 and a rugby player at university - he can decide how much he drinks but we will always caution him about excess with alcohol, especially with spirits. I have seen spring break in Florida and kids go crazy, often because they are not used to drinking much at university while they are studying - then they are let off the leash. Ask the local hospitals how many alcohol related admissions they have during that period.
I'm not saying he has to follow them around but he should at least be aware what they are drinking - he was also responsible for the other girls whose parents would assume they were in a safe environment. You said they don't have fully developed decision making ability - which is further impaired by booze - it's just responsible parenting.
