It seems to be a common viewpoint that it's "obviously" naive to think that the same political institutions could work for everyone around the world.

But lots of day-to-day-life things (city structures, school systems, increasingly even food...) seem to globalize quickly just fine.

Why the difference?

interestingly, there is probably more disagreement on some of those ideals within cities in a single country than in cities across countries.

e..g viewpoints in bangalore and san francisco are probably more aligned than san francisco and baton rouge, for example

Technowatermelon. Elder Millenial. Building Farcaster.

Viewpoints on which issues?

I wonder if there are some issues that tend naturally toward more alignment within each country and other issues where countries are all basically the same and local or individual differences matter the most.

it's less that and more "different issues within a single nationstate".

for example, where public funding goes in a large, u.s. state.  in the cities, they might like state money applied to city renewal.  in the rural areas, it might be applied to interstate travel.  more people in cities mean the money goes urban.
