The correct answer is "High cost of living".
It simply makes no sense that a person would choose to migrate towards a country where the cost of living is high. Usually the motivation to relocate is precisely the opposite: the living conditions, employment opportunities and wages don't match the cost of living in a certain region and that prompts migration.
