"When red-haired people are above a certain social grade their hair is auburn"

This quote by Mark Twain is a commentary on the social class system and the way it impacts individuals's perception of physical attributes. He is recommending that when individuals of a certain social class have red hair, it is seen as better and is referred to as auburn. This indicates that people of a greater social class are viewed as more attractive and desirable than those of a lower social class. Twain is also implying that individuals of a lower social class are evaluated more harshly for their physical characteristics, such as their hair color. This quote is a suggestion that physical characteristics need to not be utilized to evaluate somebody's worth or social standing.
