Re: Privacy concerns
I am with you and there is a fine line that needs to be maintained by a business that uses data to market their products to consumers. For example, there have been instances where tobacco companies have been deliberately placing their products at the eye-level of kids, under the assumption that kids can be converted into lifelong customers fairly easily. Whether this assumption is right or wrong, it does illustrate that demographic data could be used to cause harm.
On the other hand, businesses and the economy as a whole, needs to match supply and demand through the most efficient channel that is available, not doing so results in the wastage of capital resources in the economy. I don't consider this as a form of marketing, I feel that often times when businesses use the word "Targeting", they simple mean, locating the demand for their service, and the more specialized a service or product is, the more data is needed to locate this demand.
