Ethics is a term that is nebulous and not always easy to define. However, most people know an unethical act when it is presented. Here are a few cases of unethical behavior.

The CEO of Turing Pharmaceuticals, Martin Shkreli, quickly went from utter obscurity to being the world's most hated chief executive by buying a company that makes a life$-$saving pharmaceutical and promptly raising the price from $$13\mathrm{.}50$ to $$750$ per tablet. Most recent update: Shkreli has been arrested, for fraudulent activity unrelated to his price$-$gouging. Few tears are being shed, even among those who would defend his price$-$gouging as an unremarkable side$-$effect of an otherwise$-$beneficial free market.

Volkswagen was in the news for unethical behavior on a massive scale. Volkswagen's installation of a software "defeat device" in $11$ million Volkswagen and Audi diesel vehicles sold worldwide has led to a massive vehicle recall and an admission of guilt that has surprised many. Volkswagen misled the EPA and the CEO was terminated.

Find a case of unethical behavior and explain it to the class. Also, find an international company that you believe behaves ethically. $($Hint: On company websites you will see the corporate responsibility as indicated by the company$).$
