You mean the only ones you hear about communing as a westerner. Pretty much every geographical region has political and economic collaborative institutions for long term stability and growth, and then there’s also things like BRICS that’s not just bound by geography. The BRI is a plan so incredibly long term election-based democracies could never even dream of it, that spans East, Central and West Asia, and is economic, political, social, infrastructural etc etc. Just because you never bothered to broaden your horizon doesn’t mean the entire fucking rest of the world doesn’t collaborate with each other just like Europe and western countries in general do.
Probably something like… €400.000 to €450.000. Then I could buy an apartment or small house when I graduate and pay off my student loans in full. It depends on the city I can find work in and want to live though. There are 3 I’m seriously considering and it varies about a €100.000 for a house between the cheapest and most expensive of the three.
