I am well aware of how the community thinks, I know a relative who turned down a very nice bocher who was the son of a big doctor because he didnt want to promise that he would learn past 10 years in favor of a bachor who promised to learn for the rest of his life who came from a kollel family
(The richer bocher was not a snob or anything and I was told he was a very good catch from a very good family, just that he didnt want to promise (He didnt say he woulndt, just that he couldnt predict the future and didnt want to make a promise if things would change)
