I went through the same thing 40 years ago when I got my English degree. I went on into journalism, got into management, changed industries and started a very successful company. I did better financially than any of my doctor, engineer or lawyer friends, and retired young.  And a lot of that I credit to my English degree, perhaps oddly, because it gave learning and discovery a sense of purpose which I hadn't had before.  She should tell critics to mind their own business.
