There is no such thing as competition. As soon as a business does something that sets it apart, it’s immediately hounded by business school people who want to profit off of lowering standards and raising prices.
It’s why everything is so expensive and wages are trash. The whole point of going to business school is to ensure that businesses are always doing the bare minimum while charging the maximum people are willing to pay.
You get that when deregulating one area at the expense of even further strangling others with regulations (a regulation keeping an oligopoly or a protectionist one is still regulation).
BTW, the most common visible problem of libertarian models. They get the absolutes right, but ignore the relative. This means that those following them ignore transient processes, and the model breaks halfway.
