The notion that any individual lives their life and is rewarded based solely on their own efforts and abilities is a fiction. We all depend on the social and economic infrastructure built through our collective activity for the playing field one which we compete. Take away the roads, the communications infrastructure, the banking and trading systems, etc., and the wealthiest among us will be reduced to subsistence living. Receiving the benefits of that social infrastructure is only one half of the social contract. The other half is paying to support it. Almost by definition, the principal beneficiaries of the social infrastructure are the wealthy. They are the ones who would lose most if that infrastructure ceased to exist and by rights should pay the most to support it.
