One feature of the current emigration wave out of Greece left unsaid.

The current emigration wave out of Greece is certainly well documented and remarked-upon. It is often compared and constrasted with past emigration waves, mostly with that of the '60s that saw droves of Greeks flocking to western Europe (mostly Germany), the US etc. There is one feature of the current wave though that sets it appart from past ones. Current Greek emigrants don't seem to be sending money back home. 

Quite a lot of countries, mostly EMs, depend on worker remittances to shore up their current account balances. Greece did, in part, during the '60s and '70s. Although, detailed data regarding remittances flowing back into Greece for those decades do not exist, a simple look at secondary income balance shows that this was quite prevalent during the 1960-1970 period (flows from the EU after the country's accession in 1981 are easily distinguishable, since the secondary income balance deteriorated as the economic situation in Greece was improving and emigrants started coming back and exploded upwards in the 80s).

If we look at worker remittances data for the present period we come across a paradox. As the emigration wave out of Greece gained steam, workers' remmitances declined and as of now, haven't picked up.

Now, one can spin a ton of different explainers on this (new emigrants are young and don't have families of their own to support back home / due to EU-induced freedom of movement people take their families with them / since a lot of recent emigrants are highly educated their families are mostly well-off hence not in dire need of support / they barely make ends meet in their new home country so there' nothing left to send back home etc.) but in order to draw data-based conclusions  one needs detailed data which I don't have.

It is worth remarking that this is not the case in other countries of Southern Europe, which witnessed similar emigration waves these past few years. Both in Italy and Portugal, worker remittances picked up along with emigration flows.

Given the dire economic situation in Greece and the relevant historical patterns of emigration, the lack of remittances sent back home from the fresh wave of Greek emigrants seems peculiar but it might be explained by the characteristics of the households sending emigrants abroad as well as the households that the emigrants set up in their destination countries.
