I should acknowledge that I do not believe private non-emergency transports are included under the umbrella of "EMS". They are clearly not. If I gave the impression that I believe that they are, I apologize for not being clear. It's a point with which I am in total agreement with you, Dust.
Let me draw an analogy. African Americans are incarcerated in America at an overwhelmingly higher rate than any other ethnicity. If this fact lead me to an assumption that the majority of African Americans are criminals and therefore all African Americans deserve to be regarded and treated as such without regard to their status as individuals capable of making their own choices, any sane person would object. The accusation is a non sequitur, it just doesn't follow. The reason for this is that the issue is complex and as you correct observe about the many problems of EMS in this country, "it is much more of a systemic problem than a problem of individuals." In the case of African Americans and incarceration rates, questions of educational opportunity and access, social dynamics, recent American history and civil rights, and just good ole' fashioned American racism loom large in the discussion. It's a problem of plagued institutions, not bad people. Racism is indefensible because all individuals have integrity and deserve to be treated as such. I know it's a dramatic example but I feel like it's an analogous (albeit in a tenuous way) to this discussion; unskilled, uneducated EMS and private ambulance workers deserve to be treated respectfully as widely-varied individuals with many different goals and capabilities, despite the fact that there are massive systemic problems associated with their job and despite the "whacker"-ish tendency among many of our least qualified. I feel no no need to defend unskilled, incurious, uneducated, macho morons in any field, I just take offense at your tendency to dismiss the lot of us basics as people who seemingly by definition, are idiots because their are barely nonexistent educational requirements to begin working as an EMT.
More later...have to go do a non-emergency transport now.
