@brit, because most of the expats think first of their family back home once they received their salary..i don't know if it also applies to other nationalities but we asians are known for making sure that our family back home has a food to eat, money to pay the bills, tuition, etc.. etc..than thinking of spending here for not so important things..for us - FAMILY FIRST..

why should they complain by the way?we're here for work because of our family..not to come here to spend..
