In an era of extreme economic inequality (which is another way of saying economic unfairness) [...]We forgo analysis of the ludicrous definition of "fair" Bob Herbert uses. What the Times does not note is that high dispersion in wealth and income might be better termed "opportunity" and "motivation." Take the extreme example: complete equality in wealth. There is no opportunity for wealth to increase, and therefore no motivation to work or be creative.
In this respect, while it seems a concern for wealth and income dispersion "equality" is ubiquitous, it appears to miss inequality as a motivating factor in human creativity.
