Weird way to generalize the problem. The difficulty of learning Swedish is not the language itself, but because Swedes default to speaking English with you if they see you struggling. If you want to truly become fluent in Swedish you have to constantly ask them not to do that, and most expats get sick of it by the 10th or so time.
