(Sorry, been at a site check all day).
This site has a bit of a breakdown of which states offer the most free lunches.
Ever wondered in which states children are most dependent on free school lunches? This article will shed some light on those statistics.

I used to have a very similar opinion. Kinda got a wake-up call about 7 years ago. My youngest's elementary was giving out free breakfast and lunch. When I asked a teacher about it, she said that for about 20% of the kids, those were the only meals they got in the day.
I found that hard to believe, but a bit later, I had about 40 kids for a cub-scout meeting (my wife and I were running the local pack back then) and had them raise their hands if they had breakfast / lunch at their school and no dinner at home. IIRC, about 6 raised their hands.
When I asked one of them about it later, he said that it wasn't an everyday thing. Some weeks he got 3 square meals a day and he didn't take the school lunches. Some weeks he would get about one or two a day from home, some weeks he'd get none. While I don't know the exact situation he was in, I do know that he was living alone with his mom.
The kid didn't look like one of those kids from an African village where you could see his ribs, but he wasn't portly either.
I think there is a bit of a chicken / egg situation here too, where some parents know that their kid can get a free lunch, so they take advantage of the system and wipe their hands of it. We certainly don't live in the wealthiest suburb, but we're not dirt poor either.
Either way, yeah, again I think it is more than you think, but I agree that it's not like all these kids are holding out their bowls saying "Please sir, I'd like some more."
