You can go even farther, if less than 50% of the people studying it work in that field, maybe less than 20% work there? And their expected wages can't pay for the cost of the college education in 20 years, then it's very questionable to study in that field. Unless you are rich already.

By that metric, one of my undergrad majors (physics) is a bullshit major as very few of us went into that field. But it prepared us very well for many other fields, so I'd say that metric is not meaningful.
