I think that children are generally raised to not believe there is "risk" associated with listening to experts. This means specialists like Doctors but also politicians and military officials.
The idea that there could be a grift set up to take advantage of people in the medical space, for instance, which is highly regulated and supposed to be for the benefit of people first and for generating capital second, is not intuitive to children.
In fact a wide array of industries and services in the United States, and the world (to not be political, as some commenter said) are set up to take advantage of children or naive young adults.
Secondary education and student loans is a glaring example of this.
> The default state is for none of these services and protections to exist whatsoever
In all of human history this is mostly untrue. Humans have always formed societies, and those societies have always provided services for their people. In fact, before capitalism, most of these services were provided in-kind as a right of being a part of the tribe.
This idea that every person is born as an individual and nothing is granted to them belongs to a certain political ideology that is designed to make sure people feel entitled to nothing, and keep things in the private industry, and keep government small. But I digress.
Of course someone has to provide the service, and collect the materials for the service. And that person deserves to be compensated for that work. But the idea that the default state of a human is to be alone with nature and subject to pure individualism is simply not true, and never has been the norm, until that idea was used to justify not providing people with anything.
> Everything beyond nothing is an imperfect and unstable solution held together with duct-tape
This idea is also untrue. We've had a lot of time to perfect these things. If we can build skyscrapers and infrastructure to maintain them, we can provide these services. You are conflating political ideology and economic motivation with literal ability. The ability is absolutely there, and was in the past as well. There is something different going on that causes these systems to be "held together with duct-tape" and it's actually other humans actively trying to destroy these systems, not that they are impossible.
