I am working on your behalf to better your home. You provide me input, I manipulate the data and feed it to the machine. The machine follows protocol, activates units and conducts actions. The output of these actions comes to me, I translate the output and provide you with the interpretation of the results. Its not a perfect process, but feel free to describe another one that isn't identical except in the words you use. I always ask for that, but I've never heard of a system that works better that isn't just more unfair in your favor.
Government, better than you think, because you don't know what you're thinking is already being done.
