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?

I think it’s because political institutions quickly boil down to matters of resource allocation, and every country has a vastly different optimal use of their resources (trade, spending, saving, %, etc)
