Self- Reliance is a value to that at first glance might seem different than trust in God.
But it is not. Trust in God means you do your obligations and trust in God that as long as you are doing your part, he will do his part.
And there is an element of doing nothing for ones own needs, but simply sitting and learning, and God will take care of the rest.
But I want to claim that this approach is predicated on the idea that the highest ideal one should strive for is to be learning Torah all the time. A very Gra type of idea. And I don't disagree with it. But I do say that learning self reliance and survival skills is one of the things that is in the category of a mitzvah that can't be done by others. חמירא סכנתא מאיסורא. One must be more strict about things that could potentially cause harm more that things that are forbidden. [Gemara Chulin]. (תיקון הגוף קודם תיקון נמפש) And trusting in the "system" must definitely be the greatest source of harm I can imagine. Don't let trusting in the system you live in be confused with trusting in God.
Thus, to make a long story short. Prepare a survival kit. Get off grid. Send your kids to the Boy Scouts and Girls Scouts to learn outdoor skills, beside their regular Torah education. And as the Sages said--teach them a hard core skill that people will pay cold, hard cash for.
Teach your boys to be men. And what is a man? Is it someone who know a lot of Talmud? No. Learning Torah is very important. But it does not define what a man is. A man is someone you want to have next to you while you are in a WWI trench or in the heat of battle. Someone you can rely on. Some whose honesty and integrity and competence is beyond question. Not someone simply using the group for their own benefit.
And these qualities depend on trust in God. For without trust in God people lie and cheat and are not trustworthy because they think by that they can get ahead or gain advantage. When you trust in God you are not afraid to keep your word.
What trust in God is. It means doing your job --doing what the Torah requires of you and then trusting that God will make things work in the way he knows is right.
When Hezekiah (חזקיה) the King prayed to God when Sennacherib came to destroy Jerusalem. He said, "King David could trust in you with sword in hand. Solomon could trust in you in prayer. But I can do any off that. I have to trust in you will I go to sleep."
That is King David could do effort but that did not reduce his trust in God. Hezekiah was saying that if he himself would do any effort that could possibly take his focus of the main idea that everything depends on Gods will. So he did no effort. Even the effort of praying he was afraid could cause him to think his salvation came from his prayers. So he went to sleep and in the middle of the night God destroyed the entire army of Sennacherib.
Appendix:
(1) Self reliance was probably the most important value to my father. Or at least it was the one value that he strove to put into us kids--his boys. But obviously there were other unspoken values in our family like family values, and above all "being a mensch"--(that means in all situations acting like a decent moral human being).
(2) Now being off grid does not mean not to use a computer. There is lots of important work that can be done only on computers. At least for me that is how things are. But what off grid means is have your own solar power source.
(3) Belief in God is rational.
Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED. (You could prove the second step that everything has a cause by noting that nothing can come from nothing.) (I mean to say you you take the level of the second step up from an empirical observation to an a priori fact.)
(4)There is a story from Nachman from Uman that taught me something about trust in God, the story about the simple son and the smart son. I could not relate much to the simple son because I just do not share many traits with him. But the smart one really rang a bell in me. In the story he was always asking, "Maybe there is someplace better for me than here."
The story in short: A father had two sons. One smart and one simple. when they were in their teens the father told the that they should go and find some kind of work because he could not support them both any more. The smart one thought what is the main thing? To get married and have children--but there is time for that. Fist I have to see the world. He got a wagon going to Warsaw. He had no money but he offered to work on the way for the owners. He got there and though they were good employers he decided t to drop them and look for better paying work and more honorable. Maybe there are better employers than them. Maybe there is a better place than here. That was his constant refrain. See the end of the story. But in short the idea of Nachman was that this is a wrong attitude. And it comes from being too smart for ones own good. One should trust that the situation one is in is for some reason unknown to himself, and accept it.
Just to bring the point a little closer to home let me mention the smart son keep on piling up academic qualifications and also learned several professions. then decided it was time to start making a family and started to travel back home.
the simple son stayed in his home village and learned to make shoes and took a wife and stayed put. and since he was simple or rather dumb he knew the business only partially. So he made very little money. But his custom was to be happy always. he would get home on Friday night and ask for the Sabbath meal. his wife would cut off a piece of black bread for him. He would ask for the fish. his wife would cut off another piece of black bread. and he would ask for the soup and she would cut off another piece of black bread. and he would go wild over the supreme taste of the bread as if it contained all the wonderful flavors in the world. In the meantime the smart son got back to town and there was no place for him to stay so he stayed with his old friend the simple son. and he was never happy. and he always was complaining about his situation.
One day the czar was going over the records and saw in one of his towns there a census listing someone simply as the smart one and another as the simple one. And he sent for them out of curiosity. The simple one came and the king discovered than he really was not dumb but he was simple by choice and had made an early decision in life not to think about things [that is not to double think anything] but to accept the world the way it is and to depend on God. The smart son decided not to go to the czar because he thought it was a trick. He thought, why should the czar send for just a nobody?" At some point he convinced himself that there really was no czar at all and the county was just ruled by a senate. And he used to go around with a friend trying to convince people that there was no czar. [Rachmana Litzlan, Heaven save us!]
He fell lower and lower because of his smartness and the simple one rose higher and higher because of his simplicity.
The simple one became the prime minister because the czar was so impressed with his simplicity. and the smart son go involved in law suits.His case eventually came before the prime minister--the simple son. And right about that time a Jewish saint [tzadik, a Baal Shem Tov kind of person] came to town. The simple son went to him for a blessing and the wise son just ridiculed the Baal Shem Tov.] This kind of personality shows up sometimes among the Jewish people. No one really knows what makes them tick. But they seem to have amazingly deep insights into the world and miracles pop up around them like jelly beans.
The smart son fell into hell. And the asked the tzadik to help him. And he eventually was redeemed.
So this story could be called the redemption of the wise son.
