> As an European, so much of what has been described here is mind-boggling at best. WTF why does America have different sales taxes between counties? Why are "dry counties" even a thing? And why do healthcare costs differ so wildly?
The United States is a big place. We have a similar landmass to all of Europe. The GDP of the state of California is almost as big as the GDP of Germany.
It makes more sense when you think of the United States as, literally, a collection of states that have significant leeway in how they operate their affairs. Even individual counties can vary widely in their culture and governance practices.
Dry counties are rare and usually associated with a highly religious population that chooses to live somewhere without alcohol sales. Generally these locations are not far from counties that allow liquor sales so purchasing alcohol is a matter of driving a short distance. However, most of the people who live there deliberately choose the location because they have no interest in alcohol so it’s not really an issue for them.
