About 6 years ago, I found myself in a Minnesota college's bookstore intrigued by a little book on capitalism. There was a shelf sticker with the course number, along with the price. I wanted to buy it for my own reading, in addition to buying all the other books my daughter was buying for her classes.
I was concerned though, so I asked permission from the store manager: "Is it okay to buy this book? I'm not in the course, and in case you have just enough for the students taking it, I don't want you to be short". He looked at the title, and laughed - "No problem whatsoever, please buy it".
In other words, socialism goes with the college territory.
