I think the point is that there are things that aren't captured by looking at wealth alone. Having a college degree, being inserted in a society that ensures peace, safety and well-being, all that has value.
Yes, and (ideally) currency in an economy is a liquid representation of value. A college degree translates (after accounting for inefficiencies) to higher income potential, more efficient spending, etc.
EDIT: typo, "liquid representation of value," not "wealth"
