I'm very skeptical of their "North Star". They want the "lifetime earnings" of individuals to increase by 100x their investment. Isn't it extremely difficult to even measure this metric? That is something that would take decades to measure. You can't just extrapolate on temporary increases because people lose/change jobs regularly. They don't define anywhere in their handbook how they're actually going to measure this AFAICT.
