I guess I was wrong about that. I remember reading years ago how shockingly little revenue targeted ads actually generate per user, but that must have changed. Also curious why FB is making 3x as much per user in the US vs Europe.
Yes it is most likely to be less but not a factor of 3 simply based on purchasing power alone.
The delta there shows what that's worth.
Please don't confuse things. FB users aren't FB's customers. FB doesn't get any money directly from the (on average just a little bit) richer US users.
I think a lot of people have a mental model based on the size of these companies that they must be making hundreds of dollars a month per user, and it's good to run the numbers to show they don't so society can make more reasonable plans.
Culture may differ, but human brains work the same in the end.
