“Consciously or unconsciously, the tendency exists to assume that the locals will so value the new people that they will change their laws, their living standards, their diets, and even their cultures, in a wish to conform to the incoming expatriates. What happens is that, if the expats do not do what they can to adapt to the new country, they are often ‘frozen out,’ until they ultimately leave. For this reason, those who are considering moving to a bolthole that is a planned community should consider the degree to which that new community has made an effort to be welcome in the country. This one factor can decide whether the new community will ultimately succeed or fail.”
