Start from an article in here:http://www.washingtonpost.com/business/economy/new-study-shows-architecture-arts-degrees-yield-highest-unemployment/2012/01/03/gIQAwpaXZP_story.html
Architecture sounds like a very exciting major which combines art and science. For the majority of people who do not want to devote themselves completely to dry science or fine art, architect is a desired career. It sounds like a high socio-econ status job too. But the fact is that, there are way more architecture (and related landscape, planning etc majors) in the United States then it is actually needed.
I believe very few people feel the "calling" of one love and did not want to major in anything else. As the article says "People keep telling kids to study what they love — but some loves are worth more than others", when students choose their major, school should give them career advice and career outlook, so students are not blindly choosing to enter the job market with a over-supplied skill.
