To put things in a mildly offensive way, if you’re really unattractive, and you want people to like you, you’re going to have to find ways to compensate for being hideous! You’ll either have to build some really great people skills, or work harder than everyone else, or go into one of those jobs that’s totally unpleasant but pays well enough for you to afford the things that attract people. You know, something to keep you from dying alone in a cave, hidden from the rest of the world.
Really attractive people don’t have to build those skills, but they don’t have to, because well, they’re really attractive.
All of us moderate uggos, on the other hand, are stuck in limbo. People aren’t going to hire us for our awesome supermodel looks, but we’re also decent enough looking that we never had to develop any really amazing skills just to make people want to be friends with us.
That’s my best guess, anyway. As a very average looking person, though, my guess should definitely be taken with a grain of salt, since I did NOT develop any super amazing skills to make up for my mediocrity in the appearance department!
