its already dirt cheap in Germany for decades. Nowhere in the world can you buy cheaper food at guaranteed quality levels than in Germany. I would rather make a huge circle around Greece, food wise. Who knows what they put into visitors' food.
Re cost of living in Asia (esp HK but also SGP), fully concur. The only changes I observed in HK as the result of "corruption crackdowns" in PRC was a few shut down jewelry and watch shops. Rents seem to still be sky high. And its telling that every wannabe TV food chef schmuck now opens restaurants in HK.
I always found Germany good value, I guess it will feel dirt cheap when going back next summer.
About the cost of living in the area -HK SGp - check the demonstrations (ie attacks and insults...) against mainlanders coming massively to HK for shopping, many products are also ridiculously expensive on the mainland side of the border. Real estate still compares favourably with HK but no longer even with the poshest areas of the eurozone ( compared with similar areas in China, at least socially similar, the quality of life is still lower in China)
Singapore is expensive but the quality of life puts HK and the parts I know in mainland to shame.
