The downvotes were probably because of the injection of nakedly partisan soundbite politics. Did it add to the discussion? Plenty of room to expand and actually discuss the matter, like you did.

As far as "you didn't build that", the context was "you didn't build that alone". Seems like you agree, in general. Nothing wrong with being satisfied with a job well done, but there is something wrong with growing up in the most advanced society in world history and thinking you're some sort of rugged pioneer.
