E-Trade Superbowl 2008 commercial

The message is that E-Trade is so easy, even a baby can use it. This commercial cleverly uses age to grab the attention of the audience. The immediate question though is why they used a white baby. Was it because the majority of people living in the states are white? Why didn't they use a black or latino baby? Is it because white is supposed to be symbolize universal man? This is an image from a mainstream, modern day media frenzy--the superbowl. How is man being represented? Is it accurate? Is it fair? Or are questions like these just "overthinking" it?
