We have this implemented in Russia. Free breakfast, lunch and the afternoon tea with sweets/pastry for elementary kids. And very cheap meals for everyone else. Yeah, it was the same in the USSR, but not in the early days of RF. They only returned that policy a couple of years ago. You don't have to be a first-world country, you don't even need successful economy to take care of your kids. Because who else will? Kids are more important than anything.
