Nike's commercial is trying to show the American consumer that from birth, a dream that you may have can become a reality with their products. This is very much in tune with the idea of the American Dream, which this commercial plays on to reach to an audience and enable their products to be seen as a necessity to become what you want to become.
This commercial is effective to young boys as they can think that if they want that life then they can have it with Nike's products.
