In general people should engage in more geographic mobility.
They're also abusing the asylum process to get to stay in the UK. It's a massive problem.
It points at how miserable virtually all Albanians that get baited into traveling to UK have it
Remember that a greater number of people who stayed would have died as miserable alcoholics. Women are still beaten by their husbands in small towns. Boredom leads to drugs.
Even in the US suicides are 50% higher per capita in rural vs urban areas.
If someone is happy in a rural area they should stay. But if they aren't and they get up the gumption to leave who are you to sit in judgement of how stupid they are?
It is better to move out of towns like this. Better != perfect.
It takes one or two generations for that secondary effect of revitalization but it happens as children and grandchildren of those who emigrated want to return to their culture and find land prices very low.
I've seen it in rural China, India, and Italy before that. Even Russia had a large number of emigrant's (or their children) return during the economic book in the 2000's. Potion ruined that, and many have since left again, but it demonstrates the effect.
Eastern Europe will be the same.
