Joseph, before a Rabbi asks a BT to start paying shule and yeshiva dues out of his own pocket, I think he or she should be told he probably wont find a shidduch in the mainstream community he is paying to be part of.
I would imagine it would not be pleasant being part of a community where you are considered not good enough or appropriate enough to marry into.
-I personally would find it uneasy even being invited over for shabbos to someone who would not consider me or my kids good enough to marry into the mainstream community.
