After a little research, I found that Norway used to have school lunches, and perhaps pioneered the concept, but abandoned it after we were no longer a poor country:
"The tradition originated in the 1930s with the Oslo Breakfast. Back then, Norway was poor and this government programme aimed to provide all school children with a free meal each day. It was an unmitigated success, and later copied around the globe. "
