How should one advertise a program if it doesn't lead to jobs? (Asking this since similar themes have come up in a conversation with a friend)

So-and-so physics department has decided to start teaching more astrophysics classes, because they need more students. Astronomy with all its pretty pictures is supposed to attract students - certainly the general education classes that cater to students fulfilling their breadth requirements are very popular. The idea is to add several more astrophysics courses and offer undergraduates who take all of them a "concentration in Astrophysics", so their degrees say "Bachelor of Physics with concentration in Astrophysics". 

The problem: in that particular city - or country, even - nobody is looking for astrophysics graduates. In fact after being subscribed to "astronomy" and "astrophysics" job advertisements for more than a year, I've only seen like two jobs with those keywords, and one of them had nothing to do with astronomy or astrophysics. One could still get a job leveraging the fact that astrophysics is "sort of" physics which is a quantitative discipline that teaches its graduates to think logically yada yada blah blah. But at that point, the astrophysics concentration seems pretty pointless.

How do you advertise a program knowing that its graduates will not be able to find jobs in that topic? What is a good response to "what do your graduates do after graduating?"
If the basic degree is still Physics with a bit of astro tacked on I don't see the problem. Even pure Astrophysics degrees usually follow all the core physics classes before specialising. 

For example, my Astrophysics degree is probably about 75% identical to my pure Physics counterparts, so as long as students make potential employers aware of this, they should be just as employable as a Physics graduate.

As a side note, perhaps students should be encouraged to study what they actually find interesting, not what will get them a job. They are likely to perform better if they enjoy the material, and with better grades and an enthusiasm for their degree, the jobs will come.
