Maybe I should have kept to the first two lines then. Paranoia is running rampant here, even if it is based in a small amount of fact. I guess that when I check out at the supermarket and the cashier says "You saved $6 today Mr. Mcilroy" my data could be sent to a database that the manufacturers could data mine and determine my specific spending habits and market material to me based on that. You can fight that, pay in cash. If we become cashless, move to Borneo and live off the land.
These changes might be on the horizon but your best defense right now will be a ballot in November.
