The real reason, I believe, most wealth is acquired is to gain status. You want to spend money, not just to obtain the material objects, but to signal to everyone else that you have the power to obtain them.
The desire to own doesn’t come just from intrinsic wants, but from what our friends want, and what society tells us we “should” have.
People tend to ignore the status benefits of wealth. Most obviously because seeking status is a low-status behavior. Anyone seen grubbing for fame or new toys to impress their friends becomes less impressive.
As a result, I believe many people delude themselves that they want material possessions for intrinsic reasons. This is an unconscious effort to seek material wealth for purely status-related motives, and at the same time, not appear interested in grubbing for status.
