Why can't schools be at night?

Why can't schools be at night? We wake up real early in the morning, and come to school tired and unready to learn. Schools should be at night. Like in Las Vegas, where they have night school for kids who work at all night casinos. And children of alchoholics can't sleep at night. Why not have school at night? It's a good idea. But they won't do it. Why? the government has a monopoly on public schools and they have no competition. Night Schools are a good idea. FACT!
