Unfortunately, looks is big in this world. Good looking people have greater advantages and get preferential treatment (at least at the start).
The same goes for the color of your skin and many other things as well such as eye color and height. Sad to say, the way you look by birth often will factor in your choices of occupation, not just the way you look but your gene pool. Beautiful people tend to be entertainers and average looking people then to hold jobs that are more technical. But there are rare instances where that is not true.
But like you said, in general, better looking people get picked first. The ugly ones (me) have to work harder to find our niches in life because we are last to get picked up by employers. This is me after becoming ugly. When I was good looking, I never had a problem getting a job. After my face had aged, I had extreme difficulty getting people to hire me. It was an EYE OPENER.
I do feel sympathy for ugly and fat people, I really do. They have it hard when it comes to employment and relationships. Funny too. Height plays into it. I am a short guy and it sucks btw, I"m only 5" 1'.
