In a way, it is important to have good, productive, and more advanced people in these places, because our influence will help to make these places better. Like I always think about the mass immigration, not talking about the criminals but about the hard working people with good intentions who are leaving their homes to go somewhere else. If all of the people who are capable of making improvements to a place have all left, then now the area really is ruined and will never be fixed. We need productive and constructive people who work towards creating improvements to the world to stay and make the necessary repairs. If everybody who is capable of helping all leave, then now everybody there is not even able to work to make things better and it will only get a lot worse.
The work we do here is mostly spiritual more than physical so we are not exactly in this same situation. But I think it is a good thing to think about.
