We cannot fully let go of it, our desire for the grandiose, the extravagant, and the full on glamorous. And when I use those words, I mean more than just the glitzy and expensive; though that is certainly a major player. I am referring to a need we have to acquire, to amass about us. Trying to understand why that is, could take thousands of pages, dozens of researchers, and probably end us up with a shrugged shoulder, and a "hell if I know" at the end of it.
So, lets just work with what we have, shall we? Good. The fact is that we seem, as a species, drawn inexorably to visions of ultimate luxe, and of control of our environment, through possession, in whatever form our culture, and education creates that in our heads. Whether our conception of grandeur means huge feather collars, acres of beads, and a substantial body size, or it means impossible slenderness, and a dress the size of a pillowcase that costs as much as a new car, matters not a whit.
Perhaps this is connected to our boundless curiosity. It may be that we cannot stop, because we simply have to know what the next thing is that we can achieve. Can we wear bigger jewelry, carry an even bigger bag, have even higher heels, get yet another tattoo? Are 50 pairs of shoes too many? Are 500? How many pairs of jeans do we need?
Its not just about those with massive wealth. I personally know, and you may too, people with huge collections of t shirts, numbering in the hundreds. Why? Because it pleases them; they can afford a t shirt, and it gives them a goal to always strive for; another piece for their collection. It makes them feel special, different, and important in some sub-textual way.
