It's mad to think that children have a lower time preference than the average individual these days.
Fair play to those kids , they have their heads screwed on .
I remember doing something similar when I was younger , there was this scheme with the post office where you put stamps into a booklet, and each stamp was worth a £1 or whatever it was back in the day.
Seems like stone age stuff compared to the potential that children have to save and invest in their future now .
