Probably a lower standard of living with reduced job opportunities.
In my view Enosis as envisaged as late as 1974, (and even by some today) involving politican union with Greece would have been an economic disaster for Cyprus and most Cypriots since it would have lead to reduced employment opportunities, particularly in the Government and Service Industry segments. There would be knock on effects on retailing, etc.
1) Inevitibly Government would be run from Athens: I cannot see Millions of Greeks allowing less than 10% of their number to have an equal say in how things are done - it is worse that the 80/20 or so situation in Cyprus. However that has two immediate consequences.
(a) most main ministry functions and all the support staff that goes with them (mostly based in Nicosia) would not have existed Cyprus - the number of civil service jobs would certainly be reduced and most those that remain would probably be mostly at the lower clerical levels.
(b) Tax revenues would inevitably leach from Cyprus to pay for the Athens based civil servants, and we would be paying for it at Greek tax rates.
All of this would have a cascade effect on the local economy as out of the wages they earn the civil servants spend money in local buinessess - if the wages are being earned in Athens then the Athenian shops benefit and eg Nicosia buisnesses loose out.
(c) as a third main consequence Cyprus would loose control over spending on vital Cypriot infrastructure projects, eg Hospitals and Schools, Highways etc. as the funds would need to be authorised from Athens in competition to demand from the rest of Greece.
2) there would probably be fewer jobs in other state entities eg RiK , Cyta, EAC, etc, as again the HQ jobs would probably be run from Athens - see above.
3) Few major financial / commercial institutions would have significant major offices in Cyprus - in particular the headquarters jobs would be in Athens. That would complement the effect of fewer public service jobs in Cyprus as out of the wages they earn the bankers and insurance people etc., spend money in local buinessess - again if the wages are being earned in Athens then the Athenian shops benefit and eg Nicosia buisnesses loose out.
4)Cyprus has been able to attract offshore business in away I do not think Greece has - this contributes to tax revenues and job creation.
5) We would still have public service and financial services jobs but I suspect fewer and those at the lower end of the pay-grade. Take out these jobs that move to Athens and jobs in other industries suffer eg Contruction, retailing: I cannot see major retailers investing here as they have. That again reduces the job market. However what we be left with? A greater reliance on Tourism and Agriculture, neither of which are great payers: we would have some local light enginering and other local maunfacturing, but they too would probably be at a lower number. The Disapora would probably be larger as faced with less opportunity many of the Go getters would probabaly get up and go.
But then no doubt the apologists for Enosis would say it does not matter - these are fellow Greeks.....
