It was only facetious commenters who said not to feed children. All the children who want to eat are getting fed. The children who are poor and qualify for the federal lunch program are getting their hot meals (breakfast & lunch) every day without charge, so your "poor" children comment is mistaken. The poorest children don't have a lunch balance because they don't pay.  School lunch balances are due to parents, who have enough income not to qualify for free lunch, failing to replenish the accounts and clear the overdrawn amounts before school was done for the year. It is unlikely that most of these balances even reach $5, as once the balance goes negative, the student gets a cheese sandwich, at no charge.  

There is a lot of detail & information left out of this article, but your vision of some kid starving at school because mom and dad are too poor to clear some huge balance on the lunch account is extremely unlikely.  $13K-$14K left in a student body of 92,000 is actually very low.
