Namechanged for this as I do not want to be outed.
Given the collapse of global economies, would you rather:
(1) live in the UK and not save v much, work till 60 or later, small house, but have the green spaces, safety for women, museums/culture, travel to Europe and so on..
(2)move back to your v cheap home developing country in Asia, retire early ( at 55) with considerable savings, a large house and a cushion for DC in case they can't find jobs in the future. But few green spaces, few museums/ theatre, awful public transport and so on... Possibly a trip to the UK every year to 'decompress'.
