In fairness, coach really isn't that bad when you're four feet tall and less than 20" at the waist. The real problem with kids alone in coach is that they're still just kids - they get scared, they get bored, they do kid things because they're kids. If airplanes had, like, two small seats flanking a bigger seat then families could fly without the adult being crushed to death in the budget-tier seating arrangements.
