Sounds very considerate to the daughters of those who were moiser nefesh to remain learning to that point.
And who wouldn't let their daughters get anywhere near someone who put in the effort to make it unnecessary to need support.
For the most part, though, I don't think those are the parents that are really getting squeezed. They seem to marry people with similar sheifos and economic vistas and try to live a frugal and hardworking life together. They aren't scared of mesiras nefesh.
It seems it's the ones whose daughters are habituated to a higher standard of living, and want a more with it guy and lifestyle, but also wouldn't consider someone who has a foot in the financially productive world, who are the most in need of support. If you want the "best" of both worlds, it's gonna cost someone.
