Even if my college economics teacher just mentioned it in passing, the matter-of-fact statement stuck to my mind like velcro. More like epoxy, I would now say.
She claimed we invent our needs.
Yes, invent was the word she used.
In other words, she said that we create our own necessities. We ourselves.
For instance, we used to get along without refrigerators. Then somebody salestalked us into believing we need them. Now millions of people buy refrigerators so that General Electric, among other manufacturers, can boast that if all the fridge units they are able to sell in a year were placed side by side, they would cover the span that connects Manila to Baguio. Hah!
