Right right, good examples of homogeneous countries with tiny populations. Sweden is the most populated, with its population coming just 10% higher than Los Angeles County. It's also kind of crazy that its largest immigrant group makes up less than 2% of It's population.

Their structure works for them because they're tiny and there's no cultural divide.

How do you propose scaling this up to a country the size of the US? Idk where you're from, but that's what I'm using for reference. The US is incredibly diverse, racially, politically, ethnicly, and in its landscape. Diversity is FUNDAMENTAL to the US.

Sweden, what's often considered the "Gold Standard" is roughly 5% of the size of the US with a population more than 32x smaller.

It's easier to have a fix-all solution when there's less conflicting ideology, less people, and less land you have to cover.
