Saving money has nothing to do with EK or Dubai, it's relative just like it is anywhere else in the world. Do you have a wife that doesn't work, 2 kids, or no kids and a working wife etc. shop at Carrefour or spinneys. Hang out at zero gravity every weekend.
I save plenty, but that's me and I'm happy with how I do it. If you like to party all the time and lease a Porsche (take a look at the car park sometime.... No shortage of money at EK!) then that's your business.
