I was watching Les Miserables the Musical after a long time, and I realised many things. There were many things I noticed after studying Korean history in the 18~19th centuries for some time. Yes, there were so many people who were poor in France and that was why they rioted. And yes, France was not the best industrialized nation in Europe during the time.
But at least they had clothes with pockets in them(the idea of pockets were introduced in Korea only by the Manchus, and weren't prevalent up to the early 20th century).
At least they had paper currency, and obviously, banks and a large commercial class.
At least they had towns with factories.
At least they had large cities where industries flourished. (on that note, at least they had a sewage system that kept large amounts of human excrement out of sight and reducing possibility of cholera infection!)
At least they had an extensive judicial and police system that, at least, walked around town to keep things in order.
At least they had public hospitals where common people could go when sick.
At least there were roads crisscrossing the country wide enough for carriages to go through.
Lastly, at least the country was ruled with one of the best laws made during the time- the Napoleonic Code.
So, I wondered of things that would've happened if Korean scholars (liberals, open to Western philosophy) went to study in France and came back within the timeframe of 1815~1830. I supposed even the simplest things that they brought may have immense positive effects in Korea.
Then, I wondered what would be useful things that, if brought to Korea, would be very useful to Korea in the long term (not the things stated above). I was thinking of legislations that, if brought to Korea, may promote industrialization and technological development (i.e. patent laws)...
So, long story short, what things may be useful to Korea if they came from France during the timeframe 1815~1830?
