It is really a pity. If I had just claimed that I spend twice as much as I actually do, people wouldn't be so quick to discard the idea. However, it really is a matter of efficiency. It wouldn't surprise me at all if my neighbors spent 50%, 100%, 200% or even 400% more than me despite living in essentially similar structures and enjoying similar things. As mentioned elsewhere, it's mostly an attitude towards what money is, means, and can do for you.
