Regarding sharing the burden.
1. Do you mean like communism? Thats what share the burden means. Pirkei avos already said, that what’s mine is yours and what yours is mine, is a bad middah.
2. Kol yisrael areivim zeh lazeh does not mean share the burden. It means we need to make sure we all keep the mitzvos. Do you believe in such a concept? It is much more important for us to bring jews to keeping the Torah rather than put them in a situation where, like I said, the majority go off the derech. As i have mentioned, of all my friends that have been in the army, are no longer frum. Most of them are partiers and go to clubs and raves every night. Im talking about kids who grew up in monsey.
3. The gemara says לפום גמלא שיחנא, which means that according to the camel, the burden. A person is not expected to do things that is too much for them. Share the burden as of yet does not have a makor in Torah, except for a physical package werighing down an animal.
