UW, I'm surprizef to hear you say such things, I would figure you would know that the tech spinoffs from space exploration have been probably the single largest driver of the US tech economy for the past 40 years. Everything technical we use, from computers in cars, to our computers, to the instruments in our hospitals, to cell phones, almost everything technical that affects our lifestyle and makes us so rich can be traced back to research done for space exploration.
So, that money IS being spent here on earth, only leveraged out a hundredfold to a thoudsandfold.
