For today’s “Economics for Dummies” lecture, and we can only hope those in thrall to the “income inequality” hucksters running for President will somehow hear it, we have Chris Marschner. What inspired his discourse was this chart,

One of the great fictions of economics lies in how data is portrayed. Growth rates are one of my favorite methods of telling lies. The wage growth rate above requires a bit of basic math and economics understanding to fully capture its relevance.

The lowest quartile or quintile will have substantially higher rates of growth even if all incomes rise at exactly the same amount. For example if someone making the highest limit of the lowest quartile (say $25,000) gets a $5000 raise that earners wage growth is 20%. As we move up the line, if the highest limit of the second quartile is $50,000 and a  $5,000 raise, that rate of increase is a mere 10%. As we move up the ladder the basis or denominator gets progressively larger and if the numerator – the raise – remains constant, the rate of growth falls. Most people know this or should know this.
