How can you compare UAE and Germany ? Cultures are so different, meaning that depending on your own origins, your opinion might be very different from another...
Anyway, how can people complain about temperature and sand ? What did they expect when moving over there ? To find snow and santa ? Easy life with no stress still can be enjoyed, and I guess the less narrow minded people would come, the better it will remain.
Unsatisfied and money focussed people, please go back and stay away...or just don't blame the country, unless somebody forced you to move.
