Again, not true. The only technology that was developed specifically for space missions was large rocket engines. and "the masses" don't use these. In fact most of the electronics were adapted from comercial products. If you have specific examples please list them - oh and I don't consider Tang to be all that big a deal.
Another thing that you're assuming is that technology requires government incentives and taxpayer funding to advance. The is a false assumption. I guarantee you that things like the iPhone and iPad were done WITHOUT government funding and do not owe anything to any government lab. In fact be taking vast sums out of the free market and directing them to a specific governmental goal will greatly SLOW the pace of commercial technology development.
Again, it is true. I shouldn't have to do the legwork for lazy libs, but here:
"Smoke detectors were first developed and installed aboard the Skylab space station in the 1970s. This technology eventually reached the consumer market, and these devices are now standard household items."
Any idea how many lives smoke detectors have saved?
