I wonder what purchasing power does for one. I mean, can buying something make you happy. And if it does, what does that mean for ancient people that foraged for everything and bought nothing. What does it mean for modern humans that are too poor, financially poor that is, to buy anything.
What do we feel when we make that purchase? Some power, some accomplishment, some pride that I have something to take home, to possess?
i worked hard for that money, now I can apply it to something of value according to those that assign value and I can bring that item home and bring value and maybe happiness into my home.
Sounds like non-sense to me as I think about it. Happiness is so much more than what you can buy.
