"There's no media-driven conspiracy to alter your mind."

I think that's wrong. Forget whether it's a conspiracy or not; many things are effective conspiracies. These days, media is designed to be sticky and most media is driven by advertisements, the goal of which are to make you think you're not good enough unless you buy certian things.

Video is a think pipe directly into your brain, and I believe there is evidence to suggest that "screen time" does alter the way your mind functions.
