Oh, I know several persons who studied graphic design, and sooner or later they found a related job. It's not always well-paid (although my uncle supports his wife and two kids just with his job as graphic designer and lives fairly well), and most of the time, you end up doing advertising and marketing, which is not exactly "art". But you have still the opportunity to find something really interesting any day, and even if you don't, it wouldn't be your fault.
What kills me most, is thinking that I didn't do what I should have done, despite having the chance. The job market in my country is really bad right now, specially for young people, ok, but still I could have done better.
