EI affects all non very rich people. People leaving the country includes mostly those not that rich enough to be isolated from EI but rich or gritty enough to change country. Many just take all their savings and take a leap of faith. Once I met a person from Venezuela 'stuck' in República Dominicana because she didn't have a job (selling ice cream) good enough to save to buy a ticket for Spain, where she had friends to welcome them.
