It is because there is a disassociation between earning money and living. You eat what you hunt, you eat what you farm, you live the house you build, you trade your crops for other crops.

Today we work for money and spend money to live, the two are linked but also disassociated. I find it that the most successful people are the ones who find joy in seeing "number go up" (money go up) as their work and life. The people who want to use money are the ones who find the least joy in getting more of it.
