Emma just opened her own salon, and she wants to make sure she is complying with all government regulations. One of her concerns is price discrimination. Emma wants to charge more for women's haircuts because she knows that she will have many more female clients than male. She determines that, in her city, there is no law against charging different prices to men and women. Legally, she can set higher prices for women's haircuts if she chooses to do so. However, Emma is conflicted because she knows that men's and women's haircuts aren't very different in terms of the time and skill needed. Does Emma have a right to charge whatever she likes to each gender, or is this price discrimination unethical? (Ethical Principles Involved: Integrity, Fairness, Rule of Law, Viability)
