Will "surveillance pricing" help or harm consumers?

I don't see absolutely any incentive for a company to spend more on tracking technologies (whatever their nature may be) in order to lower their profit. So guess who gets the proverbial shaft in this equation?

Oh, come on. The whole thrust of this kind of pricing is to create higher prices for that segment of the buyers in a market that will pay it. For the most part, a mass market without information about segments of the buyers will only bear some "average" price. The extra information monopolies have about their consumers let's those monopolies create a few higher price points. This isn't about helping consumers.
