OK, here's one of those "back in my day" stories. Let me first say that during this time period, each school was part of a school "district", and was not then under any state or federal control.
When I attended high school (in Illinois) back in the mid 1960's, our parents had one of two choices when it came to our lunches. They had to sign a form which stated that their children would either pay for their lunches or they would bring their own lunches. There was no such thing as the school paying for your lunch.
Additionally, we were responsible for bringing our own notebooks, paper, pen/pencils, etc. There was a "book store" within the school where you could buy these items. If you lost or damaged one of your initial study books, you bought a replacement from the book store. All proceeds from these sales stayed within the school, and the profits went to fund other school activities, such as building a school 'float' for local parades.
Frankly, I think we should go back to that type of operation. The state or federal government should not be in charge of feeding our children. That's up to the parents, who should be responsible for making sure their children are fed, clothed, and properly prepared when they go to school.
