There comes a point when beautiful/handsome people are judged on character.
Character matters but if you are ugly with a good character people take you for granted more or don't care. Something has to allow you to get your foot in the door and that something is often the way you look at a job interview or when someone sees you for the first time. That's more important to people. They want good character and physically attractive too.
Being good looking is about PR.
Exactly. PR is what most women do well anyway. Their beauty facillitates their PR skills. It's easier for an attractive woman because people see her and they want to talk to her and get to know her better. She needs a good personality to go along with it but the physical appearance is what people see first. It's the first conclusion they reach about a person. They see someone (especially if this someone is a woman) she is ...ugly, pretty, fat, thin, gorgeous, etc. Some people have a prejudice against unattractive people and they don't want to talk to them, be seen with them, get to know them, listen to their point of view.
