As long as you saving as much as you comfortably can, that is all you can do, regardless of what anyone else is doing.
We had years overseas where a small local currency stipend was all we spent since housing and transportation were provided and the entire US paycheck went into savings. When all the overseas benefits were added on top of wages(+bonus+stock), the savings rate was like 150%. We had colleagues who, on the other hand, spent like fiends and were constantly shifting US dollars from home to fund their exploits abroad. It was cheaper than in the US so if you wanted to spill your cash you would really live the high life - people rented out entire restaurants or clubs for parties, splashed out at fancy resorts on weekends, hired all sorts of domestic staff (cleaner, driver, cook, bartender, nanny) etc.
