These are just the people that are most likely to be able to get out of the country, you bastard. That doesn't mean they don't have a good reason for doing so. Old people aren't up for the trouble anymore. People that are sick are also not gonna be able to make it most likely. It's mostly young people (not only men by the way, there's a lot of women as well), sometimes with kids. It makes sense that it's these people that are migrating. They're most likely to make it to another country alive, and find decent jobs, and they still have their whole lives ahead of them which they don't want to live somewhere in a war/inhabitable place.
