The reason we in towners have all those organizations is because there are so many more people that #1 are able to volunteer and #2 need the services! When you have a much smaller OOT community, you don’t have the either one of those nearly to the extent that an in town community has.
And chesed is not confined only to official organizations. There are many other ways of doing chesed. For example, true Hachnasas Orchim, inviting people to your home regardless of whether or not they fit your specific level of frumkeit etc, is much more common, IMHO, in an OOT community than in an in town one.
