An interview with a Nobel Prize-winning economist from India has an interesting idea that now has some data behind it. If you give very poor people (Ghana, India, Peru) money, nothing much improves. But if you give them money and coaching, you see significant improvement in their income. "Coaching" in this experiment means showing them how to do something step-by-step. Even riding a bus to go pick up merchandise to sell is complicated for someone who has never done it.
Stuart Schneiderman of Had Enough Therapy? used to be a psychoanalyst, but now in his later years believes a coaching model works best for counseling. He makes a strong distinction between teaching and coaching, mostly from the attitude of the counselor. He finds it matters.
I have done reasonably well at teaching, and being verbally encouraging is fairly automatic, but I don't think the rest of coaching comes naturally to me.
How far can this go...how much can we rescue a whole city or a whole nation...who knows? But we can get some improvement, so lets start there.
