That wasn't foresight, it was a last request.
All the teachings are available in the suttas, including advice to householders. The fact that Anathapindika was not taught in that manner reflects only on the fact that he was too busy with his affairs, and had not made time to hear them. Although he was generous with his property and wealth, there are few suttas in which he asked penetrating questions or showed motivation to learn. He seems to have been satisfied with making merit.
So based on my readings I'd say this was a sort of death-bed conversion. Perhaps Anathapindika realized he had made a mistake and asked that even lay followers should be taught in this manner as a way of apologizing for not taking the Buddha seriously.
TMingur: If by "all His teachings and not a portion" you are referring to the suttas, and nothing else, I'll agree.
I'm wary, though, as you usually find a way to sneak in some Tibetan stuff on the sly. Have you changed your mind?
