Whether its true or not, that will not be the case over the next year.

With oil prices going up and absolutely everything you will buy being flown, shipped and trucked into the UAE the inflation is only just beginning. Oil has gone up at least 25% in the last few months. The goods in the shop today were negotiated when the transport costs reflected under $100 a barrel and most commodities were at least 20% cheaper.
Expect a 25% increase over the next 6 months alone.
The pay review at Emirates will give great insight into the viability of a move here. It will show how much the salary might decline over the next year in terms of purchasing power.
