You go to the local baker and buy a loaf of bread.After you leave, he writes down, on a piece of paper, your name (he knows you, after all), when you arrived, how long you took to choose what to buy, what you bought, and how you paid - bills, credit card, etc. He also writes down if you looked happy, nervous, what you were wearing, if you were with someone, and anything else he can see.He then seals this paper in an envelope, and at night, when no-one is around to see, sells a whole bag of such envelopes to the mining/merchant/transportation conglomerate from the neighboring town, for little more than pocket-change.Would you consider such a person a good neighbor?
