Although I’d be surprised if the industrializers knew about the Sumerian model and drew inspiration from it, rather than reinventing the same thing…
But yeah, the big innovation was applying education — any kind of education — to society as a whole.

I think the big difference in the Industrial Revolution was that an attempt was made to bring ***everyone*** into the system.

Anyhow, thanks for an interesting post!
