Question about All My Sons by Arthur Miller: What is Arthur Miller criticizing about American society in this play?

Miller points out the flaw with a merely economic interpretation of the American Dream as business success alone. Keller sacrifices other parts of the American Dream for simple economic success. Has he given up part of his basic human decency (consider the pilots) and a successful family life--does he sacrifice Steve or Larry? Miller suggests the flaws of a capitalist who has no grounding in cultural or social morals.
