Question - 1: How the variations in Economic conditions of the child from pre-birth until age of consent strengthens his or her Ego?
Question - 1.1: Is it that scarcity of the available alternatives to gratify ends strengthen, or weaken the Ego?
Brief Explanation: Since Ego is nourished by the experiences, and Economics is the study of human behaviour under conditions of scarcity of substitutable means given multiple ends, we should expect that the variance in scarcity of alternatives for gratifying the ends of growing children who more or less share the same ends would play a role in relative developments of their Egos.
