Yes, I think that is broadly right: the main, fundamental, underlying problem is that people are rubbish. That's all people, I'm afraid - in varying degrees, to be sure, but fundamentally self-interested. And I can't think what we could do to change that, so look for a minute at what other big factors there are in play. I'm of the view that over-population is a huge underlying cause of misery, and certainly for the future will be the cause of a lot more. Some of the most effective strategies for combating over-reproduction involve improved education for women. And that is something you CAN throw money at. So it's not enough really to say that nothing can be done.
Academic, though, if you don't think overpopulation is a big issue.
