Well… for one, your competitors would have an instant marketable advantage over you.
What “the market will bear” isn’t what you think it is. Mars and Hersey and … idk is there another candy company?… don’t meet in a smoke filled room figuring how best to make you poor and fat. “What the market will bear” in a free market much more means what you can offer as a value before you introduce a opportunity more competition or an alternative to your product.
If your industry does meet in a smoke filled room, that is neither capitalism nor a free market.
I suggest everyone read Sowell’s Basic Economics at least once as an adult.
