Completely unrelated. The fact that most people spend a stable relative portion of their income/wealth has nothing to do with feelings. It has to do with common sense. Only stupid people feel wealthy when they are not and even dumber people then go ahead and spend the little they have thinking they are wealthy when they are actually not.
Um okay. You ask about a psychological phenomenon and then dismiss it without any basis.
Is that "keeping things factual" that you are advocating earlier in this thread?
