Countries around the world provide frightening examples of what happens to societies when they reach the level of inequality toward which we are moving. It is not a pretty picture: countries where the rich live in gated communities, waited upon by hordes of low-income workers; unstable political systems where populists promise the masses a better life, only to disappoint. Perhaps most importantly, there is an absence of hope. In these countries, the poor know that their prospects of emerging from poverty, let along making it to the top, are minuscule. This is not something we should be striving for.
