This strikes me as in principle somewhat wrong and in practice quite wrong. If American universities expelled everyone whose declared major was not a matter of passion, they would in general be pretty empty.
No I am saying that college is not about "goalposts". I truly now believe that college is not something that should be done solely to further ones career (hence, passionless students). Instead it is something you do because you are genuinely interested in a subject and want to further education. Otherwise you end up in the situation we are in.
If the goal is to have a job, there are better ways of accomplishing that than taking on student debt and pursing something you are not that interested in (or spending lots of money trying to figure out what you enjoy).
