It's not clear that concentrating so much money on a single government project fosters more benefit than having the money go to a variety of other projects. It is easy to see the items developed by something like the Mercury/Gemini/Apollo program, but we often miss the innovations created by private industry when you compare a similar total spend (Bastiat's "seen and unseen"). One example of the alternative is how (private) demand for cellular telephony has triggered many innovations, from powerful and efficient microcontrollers to bright LCD screens, and fast-charging lithium-ion batteries.
