Proverbs 27:20 “Hell and destruction are never full, of the eyes of man are never satisfied”.
Humans want ‘stuff’.
It might be as simple as a McDonald’s
Big Mac, or as esoteric as ‘peace of mind’.
We want stuff. Tangible or intangible, real or imaginary; it does not matter.
I may want ‘much’. You may want ‘little’. Does not matter whether it is plenty or sparse; it is still stuff.
It is stuff that moves us from a place of dissatisfaction to satisfaction.
I am dissatisfied because I only have 6 rose bushes. Consequently I buy 3 more and I am satisfied. I like roses.
And those who purchased them, who were once dissatisfied, are now satisfied by purchasing your automobiles.
And a year from now, I may want more roses and you less automobiles. Our desire for stuff changes.
I want ‘peace of mind’. I read my Bible.
You want ‘peace of mind’. You may visit a psychiatrist.
I am helped by my Bible. You are helped by a psychiatrist.
We both want to move from dissatisfaction to satisfaction.
Thus, we organize our behavior to move from a position of dissatisfaction to satisfaction through acquiring stuff. This is economics.
