> Just at the beginning of the article he states that humanities are only good for rich students to pass their time
Where in the article does the author state or imply this? The section beginning "When I first came to Oxford 30 years earlier..." is obviously written to be tongue-in-cheek.
A close reading (humanities skill!) of this article might highlight the following passage as the central thesis:
Universities, which in Britain have an 800-year history, have traditionally been derided as ivory towers, and there was always some truth in the accusation. Yet the distance they established between themselves and society at large could prove enabling as well as disabling, allowing them to reflect on the values, goals, and interests of a social order too frenetically bound up in its own short-term practical pursuits to be capable of much self-criticism. Across the globe, that critical distance is now being diminished almost to nothing, as the institutions that produced Erasmus and John Milton, Einstein and Monty Python, capitulate to the hard-faced priorities of global capitalism.
> Locking themselves in a room, nostalgically talking with like-minded people without ever doing anything leads nowhere.
Again, where in the article does the author suggest this course of action? If anything, he seems to be suggesting the opposite, that the humanities should be returned to their traditional place in the public square, questioning and criticizing the prevailing ideologies of the day:
It would also seek to restore the honorable lineage of the university as one of the few arenas in modern society (another is the arts) in which prevailing ideologies can be submitted to some rigorous scrutiny. What if the value of the humanities lies not in the way they conform to such dominant notions, but in the fact that they don't?
