The Business of Looking Good: Why vs. What

Interesting cross-thought here.  After contemplating Simon Sinek's brilliant "Start with why" speech, here, the thoughts eventually collided with previous thoughts-entertained revolving around the way the pretty people have an advantage in a visual environment; well spoken in audible; etc...  I wonder how deep that "why" goes.  Are the barriers, to trust/love/acceptance, fuelled by knee-jerk reactions to senses of reasons "why" someone may not be trustworthy/lovable/acceptable... If the beautiful are innately more available to success, do they innately, seem to, have less reason to be disbelieved? Just post-in-noting that for further thought.
