Going to the store and having a problem with one of the products, we looked at the registry of all my last purchases(that got recorded for using a discount card) so they could see I was right. Just looking at the list it felt so wrong. Everything I bought, with the day on it, the person that attended me FOR YEARS. I mean, they had all this information about me that even I do not have about myself so they could study me like a Guinea Pig. Governments are collecting more information about us that the Stasi or KGB. Transcribing our phone conversations, our GPS position, and now everything we buy, where we buy it, when we buy it and soon with whom we do it. This is a serious problem. We are predators by nature, the first thing hunters do is study the habits of their victims so they can find vulnerabilities. Too much power in a few hands. This people also have the power to make money, and want to ban cash so they can force you interest in your own savings(negative interest or tax your money).
