The state is made up of human beings too. I don't see why they would want most of humanity to starve. Even a power-hungry psycho wants to have people to rule over, and I don't think the average politician's neurotic traits are so extreme as to want to eliminate 99% of humanity and inherit the Earth.

Positive feedback loop (or how it called in English, idk). You just want to stay at the top, and the better political instruments you have for that, the worse governor you can allow yourself to be. And the worse governor you are, the more you develop and use such instruments. And then you can could be even worse governor. And so on, until you kill 99% of humanity because the were strongly opposing your position on the top.
