Seems to me we would do a lot more science in space if we were living/working there. NASA should really focus on fostering technology exchange to entrepreneurs who will use space to improve our economy through tourism, energy generation, and mining of raw materials.
What if NASA was using its space technologies to help design and create waste management system with the goal to reuse all of the materials previously created. Could you imagine if we no longer needed to create new plastics, rubbers, or any other raw material again. This would cut production waste and pollution, and stop the growth of our land fills. This would be an excellent way to spend our hard earned tax money. I've once heard that NASA has been provided these funds for so long because outer space technologies and advancements are whats going to save us when we have to leave earth. This seems ridiculous, almost like the government has realized the our planet has reached the point of no return and we must move on. If NASA invested the time and money towards cleansing our environments and habitats then we wouldn't have to prepare for an escape. Sorry if this is to much of a tangent from the original post's point.
