On topic: yes, there is a problem with waste.
For example, people are addicted to the $30 office chair that they can buy at Walmart for their computer desk. Too bad that $30 office chair falls apart in 6 months, as pieces of plastic break and the back falls off. So every 6 months, it is back to the store for another $30 office chair. If they just bought a $200 office chair to begin with that lasts a lifetime, there wouldn't be a problem. So much waste for a temporary (and very short lived) economic gain. I've been through many, many cheap office chairs as I grew up, they all failed the same way.
Apply that office chair idea to most of what we used to buy that was permanent but which is now disposable.

I think it's due, at least in part, to the fact that most cheap food is high in calories and generally not very good for you.
I agree with notfred. A box of Mac and Cheese is high in calories, tons of fat, has nearly nothing of nutritional value, but it costs 25 cents. So what do the poor buy? A $1 chunk of fresh broccoli or a $1 apple that feeds one person for half a meal or a 25 cent box of Mac and Cheese that feeds four kids for a whole meal?
