There are a lot of families where parents work but they still don't have enough money to cover food. Hence the school meals and other help.
If work doesn't pay I don't see that as a failing on behalf of the parents.
Of course the solution should be that work pays and benefits are enough to cover basic needs, but that is not the situation right now. So you end up with people wanting to help and offering meals, used clothing...whatever.
Schools aren't childcare. If society is failing children it's not on schools to carry the can.
