I started this yesterday but had to save for later. Most interesting that this should come up with your son. I have made several posts on the subject in the last few days. There are two things that stand out from your post that I want to mention first, the obvious depth of your intellect, and the love you have for your son. He is already rich.
The first thing that I would want to try to address is the connection between poverty and fear, between wealth and ego, the emotional foundation on which real self respect is based, that wealth and poverty have little to do with money. That is probably why the hobbits are rich, the represent being here in the world full of the capacity to love all the natural joys of life open to folk not infected by self hate. To be rich is only a byproduct of mental health.
Here is a post I gave to a proponent of the notion that hard work and ambition are what make for wealth:
"Your viewpoint is so very limited. So let me tell you, do not be anxious about your life, what you will eat or what you will drink, nor about your clothes, and what you will put on. Is not life more than food, and the body more than clothing? Look at the birds in the air: they don't work sow or save seeds and yet they are taken care of naturally. Are you not of more capable than they?
And what good is all your work going to do for you? Why strive for the good opinion of others. Just look at beautiful flowers. They didn't work to be that way. Look at a field of wheat. Today it is green and beautiful but tomorrow baked into bread. Weren't you born more beautiful than grass. No you do not trust in the things of life that matter but seek after personal gain, unaware of the infinite treasures you have. Know thyself first and you will neither toil or envy but cut through life like a hot knife through butter. You have fallen in love with the part of you that is most ugly, contempt for your neighbor's sins.
Do not worry about tomorrow until tomorrow gets here. To worry about tomorrow is not to be here today."
Perhaps you recognize that I just altered a bit the words of Jesus in Matthew 6.
Earlier in that same thread I posted this:
"Surely our system creates poor people naturally no?
How can you have economic competition without most people loosing the game. We have a dog eat dog winner take all system. My money would be worthless if everybody else had what I do. Why would I struggle to win if everybody gets what I have. To eliminate poverty would require a new kind of human being, one who wanted everybody to have what he has, one that would be happy with not too too much. Do any of you know what would happen to the oceans if the Chinese ate as much fish as the Japanese?
To cure poverty requires a revolution in consciousness and a total different system. The CBD for example, doesn't want anything to change. Maybe one day they will because China is going after our lunch. We are too spoiled by success to compete. It's going to be funny listening to American conservatives begging China for more socialism."
This notion that the problem is systemic never gets anything but rejection. Most people don't want to look at the matrix and see they have been co-opted by it, that they are willing slaves.
So in my opinion we are all born rather infinitely rich, as rich as the human ape can be. We were born with the potential to exist in a timeless state of being where the love we experience is the love we create. All that you can do then, to attempt to make your child rich is to preserve, as best you can, his natural gifts. It is, in my opinion, the destruction in childhood of the willingness to love, caused by put-downs and betrayal, that create poverty of spirit that leads to poor attitude toward life. It is this inner wealth, our creation in God's image, that is the only real source of real happiness. I believe that Christ willingly went up on the cross and gave His precioous life, so that others might be reborn in that promise and faith.
We are what we eat, so to speak, the result of the impacts of life we receive, So if I had a child with a curious mind I would want to expose him or her to as many good impacts as I could, as many positive impacts as I could that point to this hidden world, the human potential for God consciousness. In that regard there are a number of Sufi stories and works you could possible collect to offer your child. Two come to mind at the moment. Both are from the works of Idris Shah, the story of the Caravan of Dreams and the story of The Magical Horse. There is also a book of his that I think is great for kids. It's called World Tales.
