The idea that just because someone comes from an already wealthy family cannot understand what "tax fairness " is, is myopic. 
Lets give some examples of how fairness could be attained; one business is run by a single woman, she has no other family members to "sprinkle " income  to in order to lower her tax bill. Compare this with exactly the same business but run by a woman with five over 18 children who do not live at home and do not contribute to the business but can be liberally "sprinkled" with her earnings so that she pays far less than example 1. Is this fair????? I am really getting sick of whiney businesspeople who do not understand that everyone should contribute but think that everyone else should subsidise their heroic risks in many many ways.
