Why not free dinners also?

Claire Trevett at NZ Herald writes:

The Green Party has launched its election year today by announcing the $90 million a year package for low decile schools, including free after school care and holiday programmes, free lunches, and school nurses in every decile 1-4 primary and intermediate school.

So the Greens want schools to provide free breakfasts to all kids, free lunches also, and free after school care. Why stop there? Surely schools should also be required to provide free dinners also? And look by 7 pm, the kids are tired, so maybe look after them for the night also – as well as for the holidays.
