In truth, He could have done the same for all human beings. The reason why He caused man to have to work for a parnassa is that a person is constantly being tested by Hashem, and earning a living is a major testing ground. There is also a distinct benefit which this outlook provides for the person who is making the evaluation. This perspective leads the viewer to become more cautious in his own conduct and helps him avoid sin. Our sages have emphasized the advantages of the trait of being sensitive to shame.
Shame serves as a shield which deflects the tendency to sin.
Insolence breaks through all barriers which lead the way to sin. Yet, these traits do vary in their effect, depending upon circumstances. Every person is a member of a social setting. When he sins, he does not merely compromise his own conduct, but he also sets a tone of insensitivity and carelessness which others invariably notice. The door has been opened for them, as well, for when they are confronted with their own challenges and temptations, they will be less reluctant to sin.
