People in Terra, governing a bizarre little country

Imagine a country on this land where the religious leader is the eldest sister in a family, the economic pillar is the eldest brother, and the head of government and parliament is the youngest brother. Does this country have any hope for the future?
"In short, the Three Races Conference has decided that you will be the first Speaker of the Shelag National Council."
Ernst Shivaish sighed as he faced his older brother, Boss Yin, who was known for his inhuman behavior.
In this Arknights world where the timeline has veered off course, he just wants to ask the amazing netizens:
"Thanks for the invitation. I'm currently in Terra, and I've just become prime minister. How do I govern this quirky little country?"
