Reasons for dissatisfaction can be different from reasons for emigration. They might be a subset, a superset, or have no overlap whatsoever. I am also dissatisfied about certain things, but these things are no reason for me to leave the country. So what makes them leave? Is it immigration like the commenter suggested? Is it the rise of anti-immigrant political parties that threaten democracy? Is it both? Neither? Something else? The article does not say. Hell, one reason why people say “I want to emigrate” could be that they don’t know what the word means, or how the question was phrased together with the tendency of survey respondents to respond in the affirmative.
