Yes, I have. I greedily want to keep as much of my money as I can so I buy the cheapest goods available, sending money to the greedy corporation who offers goods at the lowest price.
This stubborn hand-wavy argument that prices stay high due to greed smacks of economic illiteracy and White House propaganda.
Charging prices the market will bear is considered "hand-wavy" or propaganda now?
If I raise the price of a gizmo I'm selling by 20% because my costs went up, why would I reduce the price when my costs go down but demand is still high? I like my increased profits, and so does my competition. The myth of perfect competition is a exactly that: established companies do not engage in races to the bottom, "cartel" behavior is emergent.
You've cherry-picked 2 outlying low-margin, high-velocity products where there is a race to the bottom. I counter your gas with smartphones, where Apple and Samsung are ratcheting up the price year over year, while competitors like LG are bowed out. Why couldn't LG compete at lower prices, and chose to exit the smartphone market entirely?
How does your perfect competition theory explain why tuition prices have been going up over 5+ decades, vastly exceeding inflation?

Because Apple keeps making the phone better.

I didn't espouse a "perfect competition" theory. That's your strawman. Anyhow, tuition prices have gone up because the government provides rivers of cash to prospective students. The pool of students thus has gone up drastically, and because of limited supply of colleges, and vast demand by students with fistfuls of cash (and little sense), the tuition went up. A lot.
