Speaking as an ugly person, the problem is the majority(all?) of ugly people dont want their peers.Solitude is preferable.
In my 20's, I was very likely to make a decision to work with or for someone if they are attractive. In my late 30's now, I am much more likely to only base it on the other person's ability and/or intelligence in a subject area.
Same reason smart people value intelligence a lot, rich people value money, and so on and so forth.
It might seem courteous and kinder to pretend that this isn't going on, but living in ignorance has significant costs of its own.
Now that I'm older, I'd definitely advise figuring out where you are on the scale and dating down, not up. If you're with someone significantly more attractive, you're paying in other ways--make sure you know what they are.
