In fact, education, or rather lack of it, is the most important explanation in this theory for imperfect income distribution in society.[19] Among others, see Peliano, Jose Carlos.

This condition indicates that if an arbitrarily small value, when subtracted from income yi and added to income yj,, with yj > yi, which means a regressive income transfer, the effect of the alteration should cause a increase in the inequality measure.
