Here's the thing. Just because two people seem the same doesn't mean they are perfect for each other. Like Reli said, opposites attract. If you pair a useless man with a useless woman you still get a useless couple with a useless relationship while as you pair a useless man with a useful woman or vice-versa one can accommodate what the other person lacks. That's kind of a basis for relationships.
