Americans aren’t interested in foreign languages
Europeans are required to learn a few tongues in school, and they’re even spoiled by being able to practice in nearby countries. Americans tend to get a bad rap for only speaking English, but the truth is the education system and its “budget cuts, low enrollments, and teacher shortages” are, as The Atlantic puts it, at fault. And it’s not entirely true that Americans are unilingual, either -- one in four can hold a conversation in a second language, while one in five speak primarily another language at home.
They have just a few dialects
Germany, Italy, and Spain aren’t the only countries with heaps of different accents and regional-specific vocab: Long Island University reckons that the U.S. is home to around 24(!!) dialects, each distinctly different depending on whether you grew up in Alabama, Minnesota, or somewhere in between. Sadly, valley girl is also not one of them.
