There's a clear trend that shows the higher the degree you've received, the more likely you are to think that it's OK to commit suicide.
According to the same dataset, it's true (and not surprising) that the higher degree you have, the higher your personal income. I assumed people with more wealth (and resources) would feel there are ways to overcome disease, bankruptcy, etc. other than suicide and thus find it less acceptable.
As we have learned from "The Princess Bride"... "in studying, you must have learned that man is mortal".
