one of the foundational problems with this sort of analysis is that "corporation" isn't really very well defined for this context.
If I live in some imaginary small town 1800's western America, and the owner of the general store convinces me to stock up on something that they happen to have an excess of, is this "corporations influencing our behavior" ?
If I live in some imaginary mid-size town in 1950's USA, and the local Ford dealer is on the radio telling me all about how their latest cars are just the absolute best, and this persuades me to get a Ford for my next car, is that "corporations influencing our behavior" ?
If anyone says anything to me that changes the behavioral trajectory I might otherwise have been on, how do I know if that's corporations influencing my behavior, or "just what people do" ?
