In Death of a Salesman, what effect do the expectations of parents have on the behavior of their children?
In Death of a Salesman the expectations of two particular parents, Willy Loman and his neighbor Charley, seem to definitely make a difference in the outcome of their children.
In Willy Loman's mind, success is a combination of personal and physical charm, popularity, and being "well-liked" by others. Sacrifice is not a requirement for success. In fact, bypassing sacrifice and figuring out ways to beat the system are factors that Willy favors more. These were the expectations he placed on Biff, his son. Willy also lived vicariously through the successes of Biff in school.
Bernard can get the best marks Bernard can get the best marks but when he gets out in the business world [...] you are going to be five times ahead of him. [...] You're both built like Adonises.
In turn, Biff lived his entire life not pulling his weight entirely to do anything. His plans for life were as shallow as his father's expectations. Most importantly, he never really amounted to anything important once he realized that his father's view of life was ridiculous, and a double-standard.
In contrast, Charley raised his son Bernard in a way that he allowed his son to just be himself.
Willy even asks Charley whether he (Charley) ever told Bernard what to do. To this, Charley responds that his salvation has been "not to take interest in anything." The result? Bernard, the kid whom Willy and Biff scoffed as a "weakling" ended up becoming a lawyer fighting cases in the Supreme Court. Charley, who is approximately the same age as Willy, continues to work and even ends up lending money to Willy for the latter to pay his bills. A father and son relationship based on honest work and trust paid off well.
In all, the expectations of the parents basically moved their children to make choices based also on the example that the parents set for them, and not just expectations alone. All that Biff saw and got from his father was a "cheat sheet" on how to be popular and find quick success. When Willy himself failed to live up to his own expectations, Biff lost his only role model and mentor, becoming lost in the process.
The exact opposite happened with Bernard. His father allowed him the freedom to find himself. Bernard did just that, and ended up growing into healthy, intelligent young man. This is how these two parents influence their sons in Death of a Salesman.
