Supposedly, a relatively smart + educated young woman from modern society is transmigrated into a body of a woman living in a country that is similar to 17th-century Europe. Monarchy and nobility exist. The country practices cross-border trading with other countries —> free market economy. Religion takes part in politics. Human rights are underdeveloped, e.g slaves etc.
Edit: sexism is not a problem in this world, meaning women can participate in politics and such.
What kind of political/economic or medical policy can they suggest to improve the country (in modern standards), without hugely offending the higher-ups?
