Taking from some citizens via taxes to give to others via welfare programs is not the sole extent of government activities, one would hope. I suggest studying the nature and extent of constitutionally limited governments before Bismarck introduced the Welfare State as we know it.
My point is not that government is corrupt; it is that politicians under a Welfare State have increasingly corrupt and manipulative designs, and that the further these designs are enabled by information technology the closer we get to a totalitarian society.
