There are certain things in society that should NEVER be treated as "for profit" businesses. They are the core and vital things that a society needs to be healthy and productive. They should be available to all citizens without regard to their wealth or status.
Those things would include:
- education
- healthcare
- vital infrastructure
These are not things that should only be available to those that can pay the highest rates private corporations can charge. They are things that should be considered basic rights of citizenship.
Profit motive is all about giving people the smallest amount of a good or service that they can while extracting the highest rates possible for them. By its very nature profit motive excludes those that are too poor to pay the highest rates that "the market will bear". By its very nature, it means that the rich will have access while the poor will be excluded.
That is the main reason our healthcare system is so badly failing us. Those that talk of privatizing our public schools are deluded into thinking that we would see competition create better education for all. That is no more true than it has been for our healthcare system. It would result in great educations for the rich and none or very poor educations for the poor.
The same is true for notions of privitizing vital infrastructure like roads and bridges. Access to them would be restricted tho those that could pay. They would be built using the cheapest methods possible while the highest tolls possible would be charged.
There are vital things that are required for society to prosper. Access to them should be guaranteed, not rationed based on socioeconomic status. The only way to guarantee that access is to have them be the domain of the government, taxes and law. They should be guaranteed public services. Not privlidges available only to those tha can pay the inflated rates charged by private firms.
Privitization works fine for things that are not vital needs. Home electronics for example. It is a disaster in the realm of things that all people NEED and which society significantly benefits from as a whole.
