Also, to @rso, I want to point out that while Shluchim get kavod from each other, it doesn’t pay off the Bizyonos that Shlichus comes with.
Unlike Shul Rabbonim and even Kiruv Rabbonim, Shluchim deal with people who aren’t Frum and often don’t care to be Frum. And there is no contract with a board or anything. You want food, you’ve got to fund-raise from these people who never asked you to come there to begin with. And as soon as someone starts becoming too religious for the community (when they start needing a normal Frum school, community, etc.) the Shliach often recommends them to move to a larger Jewish community and loses contact[1]. And while some are lucky to live within a driving distance of other shluchim or Lubavitchers, there are plenty of Shluchim see each other once a year, if they’re lucky. And these Shluchim also have to send their children away to board (by grandparents or uncles) since it’s unlikely that there’ll be a normal Frum school within the area. And while these kids do grow up Frum (I know a few Rabbonim and Roshei Yeshiva who grew up this way), it’s not easy to send a child half way across the world, even if he’s going to a grandparent.
Tell me, do you think that getting a once a year Kavod by the Kinnus is worth it?
[1]. And even if they don’t, the BT has to give Maaser to his new community (Bnei Ircha), so he can only give whatever leftovers he has to the original shliach.
