What if the goal of an economic system was to support everyone instead of maximizing the upside for winners? Perhaps that's the sort of change necessary for improvement. Perhaps having billionaires is the failure state.
A goal fails - who sets a goal? The keyword is system.
An economic system needs something like a Nash equilibrium where defectors are sufficiently discouraged (and cooperators are rewarded as you imply). https://en.wikipedia.org/wiki/Nash_equilibrium
