Free food for the rich ?

I was talking with the Cuban refugee I work with the other day about what school is like in Cuba and he told me most kids go to school because that is where they get their meals. I guess they have a very "open" casual attendance program where you go to school when you want and leave when you want but most kids stay for the food. This was all in the context of how disappointing he was in the school food here. He said while it tasted fine the portions are so tiny compared to what they fed him at school in Cuba. One possible reason for that : The lunches in Florida schools are now free for every child. Now I am guessing the district is going to be saving money by not having to monitor who is on free/reduced lunch and that is why they are doing this. But if school lunch is free for everyone doesnt that mean more kids will want school lunch? How will an increase in demand and the loss of income from the families who could afford to pay change availability and portion size? Also being lost is the economic/responsibility lesson tied in with lunch money (and the bully aspect which comes with valuable life lessons of its own). Just food for thought.
