best analogy I can think of, for the average ugly person, is being born into poverty but being about the same as other people in your other attributes.
looks are a lottery like lots of things in life and you're pretty lucky if you have good looks
Probably breeds resentment that you have to work harder for the same respect etc.
What an awful thing to ask. Just because you look 'beautiful' doesn't mean you have the privilege of trying to ask 'ugly' people about how it feels to be ugly.
