We can never capture all the value we create in the world. The more value we create, the smaller proportion of it we can capture.
Education is the quintessential example of this. Preschool is an incredible investment [0] but the payoff happens far away in time in space. While you can't capture the value generated by running a great preschool, you certainly benefit from a community of adults who had strong early childhood education... thanks to investments from other people at some other time & place.
An expansive mindset is required to benefit from these kinds of investments.
We can be realistic, or we can just surrender prematurely. The latter can be dangerous.
