Sorry to say this bud but china and India are by far some of the worst ran countries I have ever seen. China has literally let millions upon millions of people die just last century fukking up their economy and doing jack shyt about that awful famine. And India, has a widespread raping problem because they didn’t do jack shyt about their socioeconomics (wherein both countries are having a conflict of men needing to be ultimate providers to women, yet making it out of poverty is incredibly hard, while there are also more men than women). So all in all, it gets progressively harder to manage a country the bigger it gets but I’ll add an extra bit, the slightest bit of corruption will do even more damage to a 300m population than a 5m population just due to the global influence of the former.
