And now, the start of my "essay" written a couple of days back - working through each point I wrote and posting a couple at a time - didn't want to make one enormous unwieldy post.
The question I am discussing, in response to what
@Swank queried, is – how can you make improving the world in a fantasy, primarily using non-magical methods, work for ordinary people in the face of military, political or magical power held by those in charge – or at least those who consider themselves the top of the heap. I am primarily using Victoria Goddard's writing as an example, and also bringing in some examples of real-life historical events for comparison and support.
POINT 1 Stability often benefits high as well as low
Taking a couple of examples from the 17th century, which is history I've read the most about (in a re-enactor and amateur way) more than surrounding centuries.
In the earlier part of the 17th century, King Charles 1 went on a visit to parts of Europe, including crossing an area which had been devastated by the 100 years war. This wasn't devastated in the sense of burnt down houses and missing people, it was trampled flat and they rode across mud – no trees, fields, houses, animals, nothing. I seem to remember it was for several days and they did see a few bands of ragged skeletal people wandering around but that was it. This was written about at the time and quite well known of – in a horrified way. So the destruction of a long war was understood and feared.
At the outbreak of the English Civil war, Parliament and the King sent out “commissions” to every country, carried by their noble representatives, authorising the aristocracy and gentry of each county to raise regiments. Across each county households chose which to follow. Except for a northern county, I think it was Cheshire, where all the notable landowners had a meeting and basically said “we could do this, but we'd be fighting each other, and trampling our own fields. Why don't we tell them both to go away?” which they did and that worked for a year or two though the war turned up in the end.
So in a pre-industrial setting, people knew they had a lot to lose from war, and a lot to gain from stability. You can improve your fortunes by going to war and seizing lots of loot, or you can work on making your farms successful and invite silk weavers to come and live in your towns and make your wealth and comfort the slower way. Obviously there were wars, but there were also periods of peace. In a fictional fantasy scenario where you are gradually improving the lot of the low – which could lead to a healthier workforce and fewer desperate beggars or bandits – it might be introduced as a pilot trial in one area where everyone around can see the benefits and then say “ok, not such an awful idea after all”.
The pilot scheme methodology is one of the many used in Victoria Goddard's books and even the doubters and those actively against were grudgingly swayed by seeing the benefits, or seeing that the downside that they'd doom-mongered had not come about.
POINT 2 The person in charge can be a decent human being and so can other people in positions of influence
Doesn't always happen by any means, but there are of examples of employers wanting to provide good conditions for their workers because it was the decent thing to do, rather than being totally ruthless. Some large landowners took pride in having well kept houses for tenants on their estates (though in some cases they crammed in an awful lot of workers in that outwardly nice looking accommodation).
In the 18th century, I learned from a documentary on sweet making, there was an early Fair Trade movement as part of the larger movement of the emancipation of slaves – sweet shops would advertise in the window that no slave labour had been involved in the production of the sugar. So such movements are not unique to the 21st century – they can plausibly have their place in a fantasy that is based on that kind of historic period.
Having a decent human being in charge, is key in Victoria Goddard's book – the Emperor (unlike several of his predecessors) cares about people and hates corruption and he supports and aids Cliopher in his work. In Terry Pratchett there is a similar approach, as in an indirect way I think Vetinari supports Sam Vimes – he certainly likes to wind him up and point him at targets and those targets are ones that a decent man would choose for destruction.
