There are legitimate functions for government. Socialism constitutes 60% of government spending leaving 40% for those functions that are defensibly legitimate. Our armed forces are superb. You are naive if you believe most of the other functions you list are of excellent quality and intellectually challenged if you don't realize that many of the things that function acceptably are in spite of government meddling. I would add that it is questionable whether government has any defensible role with regard to the economy.
"Amen!" to the general thrust of your comment, but I think at the federal level it's closer to 15% legitimate and 85% socialistic.
