Other than family and perhaps saving for a nicer retirement why would you go home?
I'm abroad (Canada) since July 2019 and the main reason I want to go home is family. Vacation days are more plentiful in Ireland but rent cost, employment opportunities are about the same and possibly worse by moving back. Travelling from Ireland, on short city breaks is more affordable too Vs air travel in North America and some food I am nostalgic for but overall Canada has good opportunities for me.
