You have a point. And, at the same time, it is possible to make very good use of college. My grandfather on my father's side would have agreed with you, but his son, my father, went to college and went on to get a Ph.D. and had a very successful career as a professor. Meanwhile, my mother's father was a professor back in the day. My brother dropped out of college, but did very well as an auto mechanic. Still, it was very clear that his two years of college made him a better problem-solver than most of the auto mechanics around him, who had less schooling. They looked up to him and came to him to solve their bigger problems.
I found college valuable because I used it to become an open-minded thinker. I learned to think well and to understand a whole lot about the whole world. Others use it as a stepping-stone to a profitable career, such as doctor or lawyer. Others can find their way without it.
My wife has many students who are coming back to college after a lifetime of work, and finding that learning to think and learning about the world is a great gift.
I encourage everyone to think for himself or herself. Let's all do that, with or without college. Then each person can decide if college is a useful step in his or her own life. And there are other ways to learn about life beside college, Mountain Man!
