"How will the people of these countries survive in later years without a working population to support them?"
Hate Do you now oppose Albania's application for EU membership ?
I thought you were frustrated that it has been delayed
Losing the young and / or talented was also a worry in the USSR, which they solved by shooting people who tried to escape
Sometimes the interests of the state clash with the wish of individuals for a better life elsewhere
However, as the EE economies are boosted by EU trade and development funds, the people should return
This is what happened in Ireland, which had been exporting people ever since the horrific Irish Famine,
but the prosperity it has gained from the EU meant that they now keep most of their young people
and iirc its population is not higher than for some time
As pp said, all Western countries suffer from declining population and declining % young people, because women don't want to have as many babies as previous generations.
Germany's population of 80 million is prdicted to fall to 55 million by about 2060, so politicians are putting in all sorts of financial encouragement to mothers and ways to make their lives easier
e.g. maternity workplace rights, v v cheap nursery
I agree with red that we don't want to keep increasing the population, but we also don't want it to drop sharply, as that would bring massve problems,
A very gentle decrease maybe, so we can plan for the future ?
