I think people tend to move where the economy is hot. The reasons are obvious: it's not fun sitting at your mum's house, while everybody thinks you're a loser,

I think people tend to move where the economy is hot. The reasons are obvious: it's not fun sitting at your mum's house, while everybody thinks you're a loser, essentially because the economy is averaging negative GDP growth year on year, and nobody is getting hired. That's mostly a social thing, not a lifestyle thing. Being unemployed in Italy (or really anywhere) is worse than having a decent job basically anywhere else.
