It is a bad step as it is usually taught, though (that is, as and end goal itself rather than, for example, as a means to better investments). Any astute kid is going to look at the “compound interest” argument as laughable. It only works if there is sustained, substantial additional contributions over a lifetime. This is especially true for people in lower income brackets. Try convincing a kid with even modest arithmetic skills that saving $2 (or $20, or even $200) and letting it compound is “smart.”
