  | 
  | To expand on the question's unknowability, "wealth" and
  | "prosperity" are measures on a population's utility functions.
  | "Utility" is an attempt at mapping the set of possible things a
  | person could want to an ordered set [1]. This goes to the heart
  | of preference, free will and consciousness.
  | 
  | Fortunately, at a population level, persistent effects _do_
  | manifest. But we don 't know why. Because at the individual
  | level, they're inexplicable (if existent at all).
  | 
  | This is why, by the way, economics often finds inspiration in
  | particle physics. Not because people are particles. But because
  | it's a field that has developed techniques and methods that
  | make useful population-level predictions without completely
  | understanding the individual components.

  | 
  | There is a tension between maximum employment and stable prices

  | and more people may be employed to keep up with demand. But if
  | there's too much demand, and not enough supply, inflation
