Despite my respect for the originator of the quote, I don't buy the cliché that the UK and US speak very differently. There are probably far more differences between regional accents just within England than there are between English and Americans. At least in the business world, perhaps unfortunately, we sound very similar.
However across Europe, things sound very different. Yet they look broadly the same. Old buildings, little roads, people on the streets. But it's weird, people are talking incomprehensively. In America, you can understand the language perfectly, but the look of the place is completely different. Not because they have fundamentally different goals and aspirations from Europeans. But because they have more space.
