IMHO, humanity's goal for the next hundred years is to enhance our energy and medical technologies as quickly as possible. (space takes a distant third).
We are essentially in a race against time: if we are too slow, we will deplete our resources and wipe ourselves out.
There are lots and lots of things that are worth a single human's life (or tens, hundreds of lives). Research is one of them. For instance, if we could magically trade a random 100 lives for knowing if there is extraterrestrial life, I believe that it's a worthy trade. That's just one example.
You know where there are lots of resources? Space. Recently ran an economic projection for a venture that was being proposed out of Russia - tugging an asteroid of copper into orbit around Earth and mining it would alleviate the environmental impact of surface mining while cutting the price of these materials to a fraction of what they are today.
Speaking about energy, check out space-based solar power. I will be the first to admit that present conceptions are as pre-mature as the solar industry in general, but, it is theoretically a vastly more efficient way to generate power than other options, barring nuclear.
To make an endeavor feasible, it would really have to be a GX large-scale multi-nation effort, and, the agreed (tacit or otherwise) collapse of certain industries (like, collapsing copper pricing, etc.)
I don't believe the current socio-political-industrial-financial mechanisms in place have any desire (though don't actively "conspire" against this sort of thing), as its too "long term" thinking, and, is really more a "species survival" deal vs short-term profit gaining.
Wouldn't be more expensive than anything the oil or heavy infrastructure majors undertake on their own today. Yes, a multi-billion dollar project all in, but that occurs in stages.
The time horizon is a problem. But everything I said fits the 4-10 year infrastructure ROI test. Not that I don't expect the first projects to have anything short of heavy government involvement.
