@icarus Lewis's whole vibe (and I'd say that of Tolkien's too)seems to be a rejection of modernity, and a harkening back to apre-industrialBritain.

And how! In fact, that is the point of MN, in particular, when it goes back to the pristine innocence of Narnia's creation, and how it has been marred by the warring, jealous, angry, lustful, "entitled" and utterly immoral Jadis' arrival in Narnia. I can see that also in Tolkien's work as well, especially in "The Shire", where Hobbits live, if not over the Ditch, in "Middle Earth", itself.  

But to get back to pre-Industrial Britain, you'd really need to go back to the late Middle Ages, for something like Narnia, when lustful Edward IV of York was king, or even Henry VII Tudor, before the Age of Exploration really got going, in 1488, & before the Renaissance, Reformation, and...oops, ..."colonisation" (gasp! shock! horror!), which as far as I know, reached its peak in Great Britain's case, in 1888, during Queen Victoria's reign, when Britain claimed Papua, to the north of the mainland of Australia, only to gift it to Australia, itself, in 1902, formally part of Australia in 1905, when the Papua Act was passed. And it is my guess, that though other nations, Germany, Belgium, France, The Netherlands, Denmark etc also had colonies galore, right up to WW2 & beyond, including long histories of failed settlements in Paraguay, Australia & in even USA, itself, it is "colonisation", itself, that is the latest bugbear & issue, that Netflix might well be tiptoeing around, rather than just industrialisation, already on the nose with some, anyway.
