Yea, it's nice to see all of the neat technology that came from our space missions, but it really was not something that government should have been spending our money on. If space exploration has any real value, some private enterprise will take on the task and do it better for less expense and more ROI.
Most major developements prior to the 20th Century influx of Communist/Socialist idealism were conducted by private enterprise. Although we wouldn't think so from Obama's criticisms of American business building, the initial infrastructure of the U.S. was put into place by private enterprises increasing our infrastructure in order to increase their commerce. The railroads were the most influential in this. The same thing has occurred throughout history. The reason for Europe, Asia and Africa's being linked together was completely due to the developement and expansion of trade routes.
