Sorry - but you are wrong & deluding yourself - inequality always worsens. Maybe you can show me wrong?
I did analysis of inequality metrics in 2014 and was shocked - thought I may be mad. Below is from my site:
Look at the methodology of Lorenz curve - a propaganda tool so you do not compare incomes to each other.
Instead of comparing incomes, sensational misdirection, you compare all incomes to a 'perfect equality line'.
The calculation merely compares poorest 20% to just an average income, then continues underestimate rest.
The Lorenz curve is basis of the Gini coefficient, about which all economists lie, saying it measures inequality.
A Gini coefficient cannot be used to compare counties or even one country year on year - a demonstrable fact.
