Those famous "educators", Campbell Brown and Dan Senor, on attack against NY teachers.

18. I'm neither critical of it nor thinking your post is confusing.

The graphs show sometimes overlapping interests, sometimes not.
There's no indication of how the MSM, which is totally involved in your graphs, is connected with the Waltons and other individual billionaire families.

Any average person (not just the Waltons) can invest in the MSM. Most, I think, invest collectively, without conscious thought, as part of associations intended to bring people wealth.

I think a further synthesis is required, to understand the economics, but I can't supply it myself.
But I think it should be a topic of conversation.
This is why I said there was a "mixture of categories".
IMO the MSM is some kind of lynchpin. Not an actual actor, in itself, but an essential part of the means, of the mechanics. At that, perhaps more central than the Waltons.

Your topic started me thinking about how even so-called "homeless" people have an economy, a system of trade, a rationale that makes each individual unique. Their lives worth living. That's how far off topic I can get.
