People wants to get better healthcare or education. Maybe they are looking for a better job for high standard of living. If the people who is really poor then the only way is to move to MEDCs' countries
If you do not wish to answer honestly, then say something like "you wanted to develop your career and felt the change of job was necessary to your developmental experience".
You can't. Part of life is losing people you like and having to move on from that. An amazing teacher leaving is sad, but there is a reason for him leaving. Maybe he needs a better paid job to pay his bills, maybe his job is affecting his marriage, maybe he was promoted.
