Grouping these people as conspiratorial is unfair and seems politically motivated. While you definitely have some overlap with conspiratorial people, people have a right to be skeptical of medical care, which is often incorrect and potentially life threatening. Being able to explain things concisely and with evidence is a core skill for a nurse, much like being able to explain to someone why their technical decisions are setting them up for failure is a core skill for a software architect.
But from talking to nurses, this isn't the drive for negative workplace satisfaction. Patients who are hospitalized are less likely to be mentally stable: many pathways to hospitalization come from extremely poor decision making, and many of these people are repeatedly hospitalized. Combine this with the fact that it's a very physical job, primarily handled by women, and you have a multi-faceted problem that's not as easy to solve as just giving people right-think.
Personally I think the pathway to fixing this is appropriately valuing nursing care, what is often a highly-skilled profession with large physical, legal, and downstream risk, and compensating people appropriately. While nursing is a disproportionately paid job relative to educational requirements, current compensation really doesn't accurately account for just how demanding a job it is.
The amount of nurses you see who become addicted to painkillers, benzos, etc., is truly sad. Much like teaching, it's an area where I feel that society is inaccurately evaluating what the overall impact could be if the role functioned well.
