Absolutely not. There’s a world of difference between saying they don’t really care (motzi shem ra, IMO), and saying they care deeply, but either have other priorities, or don’t “control” bochurim the way you, pba, and others seem to think they do.
Semantics. It is like the old joke that someone loves getting the flu, it is just way down on the list of things that he loves. They may “care” about singles (in the abstract), but they care about supporting kollel bochrim and keeping them in yeshiva so much more that the other doesn’t come into the picture.
I’m not saying they “control” anyone, but they did manipulate they system (as you point out one way, the absolute disregard for planning in Parnassah is another) and they are pleased enough with the consequences that they have no interest in making serious changes.
Finally, we can argue about how to help “older” girls on another thread.
