Of course they are both salesmen, but the dramatic situation is one where the men's personal moral codes are challenged by their circumstances. In both plays, the business world is changing for the worse. The men are finding that the "dog eat dog" competitive world where they once thrived is now eating at their very souls. Willy's (1949) request for a new route, closer to his family, results in his getting fired, but the problem is not his competitors. In Glengary Glen Ross, Shelly (1984) is in direct conflict with his fellow-salesmen; the two playwrights are decades apart both in real time and in the world of business where they function. As playwrights, Miller and Mamet are very far apart -- one important difference is the three-act vs. two-act play format, which both require a different structure of plot and resolution. The important similarities are the necessity of resorting to questionable acts because of business competition. The important difference, however, is that we see Willy's home and family environment, and at the end of his career, but with Levine we are always in the business environment, so Mamet can use his own business experiences to build the Shelly character. Willy is much more sympathetic, and much more a Jungian character type (Will He? Low man), while Shelly is closer to a real criminal type, who will disregard the law for his own profit. They are both dramatizations of what the business world does to individuals.
