What markets function like this? I have no idea what the cost of growing, harvesting, shipping, and selling a banana is. At every step of this process there are capital investments, labor costs, and profit margins that are totally opaque to me. And yet I can look at the price of a banana and decide if I want to spend the money or not. One beautiful aspect of markets is that not everyone has to spend years researching every purchasing decision. The makert sets a price for you. If one company has margins that are too high, another steps in to take some of that profit, by offering at a lower price until it reaches equilibrium.
The job market seems similar. I don’t know how companies set their offer price but I am capable of evaluating offers all the same.
