You're wrong. In addition to new discoveries, fantastic technology is designed to support space missions. Technology that carries over to the masses and is used and enjoyed by the world today.
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.
And - when liberals take over the whole planet, we have somewhere to escape to.
