It’s not true that all learning boys only want girls with money. It’s just not true. There are those who do, and those who that’s not their priority. I wonder why you’re being exposed only to those who want money??
I know many boys from chofetz Chaim yeshiva are not looking for wealthy wives. They’re taught to want to learn and go into chinch and many that I know of married regular women from normal families who’s families did not support. The women also didn’t have amazing careers. They became bookkeepers, secretaries, teachers, worked in offices etc. they were prepared, both of them, to be moser nefesh letorah.
