What if incomes grew like GDP?
I always like to say that we live in an <i>exponential meritocracy</i>, where your accumulated merit enhances your ability to accumulate more merit, eventually resulting in a small minority rapidly pulling ahead of the pack. Goes with the old adage: turning $100 into $120 is work; turning $100 million into $120 million is inevitable. Perhaps we need a linear meritocratic function.
