Even without inefficient Totalitarianism, New Holland would have a tough time feeding itself. The whole island put together simply can't support the 63 million people it has. There's a reason New Holland's biggest export is people, followed only by the few raw materials that haven't been picked clean.
The biggest problem for New Holland is that they are historically a settler colony, but unlike the colonies in the Americas never really had anything valuable. Sure, the Netherlands established New Holland in the 17th century as a way to both get rid of prisoners and extract resources, but soon after almost all of the Netherlands' food needs were met from their North American Colonies. It was always a lot cheaper to grow food in the Americas, and due to distances involved cheaper to ship it as well, so ever since then New Holland was principally just good for subsistence farming.
This didn't stop the high population growth of settler colonies, and once you fast forward a few hundred years New Holland has run out of space to farm. Once oil and other resources dry up (and they damn near have), New Holland has little left to offer the world. They're out of the way of most sealanes and the Netherlands never bothered to invest much into them. It was pretty much inevitable that they would become the poorest Western State in the world.
