It is actually the opposite. The less things you have, the less things you will want.

I even experience this with food. If I am on a strict diet for 2 weeks and then have a "cheat" meal, a previously normal meal feels like a satisfying feast.

If I splurge on food for 2 weeks, even 3/4th a pizza doesn't satisfy. I just want the other 1/4th.

It is really why we have so much wealth as a society but so much discontent. It is like believing there is some amount of alcohol that would satisfy the alcoholic. It just grows the desire for more while contentment is harder and harder to achieve.

I am pretty sure this is just a property of the dopaminergic system.
