Europeans seem to vastly overestimate Americans ability to afford to do that.

This part, I'm struggling to stay afloat I can't splurge for a intercontinental trip. I can, however, drive my car for a day or less and be in a completely different biome/culture. Each state is essentially it's own country with it's own laws and cultures. An overarching American influence but each place is definitely unique to itself.

I like to learn a language not so much out of practicality though because you're right, we can speak to everyone here with English. I like to learn a language just for the mental benefits of training my brain and learning more about another culture.
