It's kind of weird that Romania has done so well, given that amount of turmoil in Romanian politics and Romania in general in the last 20 years.
Basically, it went up for Romania because they got access to the EU market (in terms of both exports and remittances) starting in 2007 and that helped, _despite_ everything else that went on. So.. kind of a win for Romania and the EU, I guess.
Smart young people left for rich EU countries: doctors, engineers, even construction workers left. It took time until the old generation that remained behind retired and now we have the effects of that: better paid jobs.
When I started working as a doctor in 2007, my salary was ~150 euro/month. It is now ~2000 euro/month. Some of it is experience/seniority, but most of it is just jobs competition from richer EU countries.
The generation during the population spike following the communist regime's 1967 Decree 770 (banning aborition and contraception) is up for pensions in about 7 years, which will create a pension crisis and a default of Romania's state pension fund. We'll see its effect on household income per capita, but it will certainly be under pressure. They already have increased labour taxes, thanx to the former goverments' deficit spending.
