I don't think as of this moment in time there are too many people in the world. However, the problems of work/food/water/housing seem like a population problem but it is more of a resource allocation problem. I think humans have proven we are bad at resource allocation/management when money/status influences it. My thinking is that history has shown that when humans exacerbate resources they shrink back/go away (ghost towns, abandonded civilizations, etc.).
