I'm sorry, but few if any of the things on your list are things made more affordable by the government. For example, flood insurance only exists because the government created it. Ditto for GPS. I am not sure how you think the government made phone service more affordable (there are two possibilities, places where there would not be phone service if not for the government...or at least not until long after it was made available there, or the break up of AT&T's monopoly, which only existed because the government created it in the first place). As for food, my food is MORE expensive because the government decided it was a good idea to use food for fuel. I am hard pressed as to how you think that postal service has been made more affordable by the government.
So, care to try again?
