Reply #84: fair is a relative term. The doctor had the advantage

[bbgrunt]

of living in an economy where people have enough money to pay fees to doctors (instead of simply providing him/her with a meal or a few chickens) and that is due in no small part to the existance of a strong middle class.

Secondly, the doctor's education was probably supported by taxpayers through a strong state university system and a historically government supported public health system.

While it seems that the doctor applied him/herself to acquire skills to perform in the job, he/she also has reaped many advantages from living in this society instead of some undeveloped poor country without the infrastructure and income distribution to pay them so generously. What is unfair about asking them to support a progressive tax system that helps maintain that society and a strong middle class? Just ask how many would rather have been born in a third world country--or how much they would be willing to pay to have been born here instead.
