I've wondered the same thing about the Ark residents considering it started off as stations from different nations. I agree that it makes sense for English to be the primary language to make for easier communication, but it irks me that everyone has an American accent. I really feel like each nation would be adamant in teaching their descendants their native language (to keep their culture alive in the event that they return to Earth, I would think), and so even if they all do speak English, some would have an accent when they spoke it.

In regards to the Grounders, the setting of the show is the eastern United States. It's realistic to think that they speak with an American accent because that's how their ancestors spoke and that's how it's been taught to them. Though I find it odd that they haven't developed at least a little bit of an accent considering Trigedasleng is their primary language and that has more of a creole sound.
