It depends on how you look at it. My expenditure is about 10K per year, which is not very much compared to other people on this forum. However, compared to the people I know, I have a lot more wealth than they do, and I own an apartment, which most people at my age don't. Also, I can afford to travel more.
I always wondered how people could spend so much money. I feel that if I have a decent size house (100 sqm), a good family, a car ($10K) and the money to travel once a year, then I have everything I need in life.
