Why hello, I think we have a winner here.
There will always be a time and place for volunteerism, yes, even in EMS. America is far to vast and different a country for every single part to have a paid, 24/7 department. But the the places that should actually have volunteers are far, far fewer than exist today. As in, think of BFE Montana, Wyoming, Texas, Alaska, maybe the UP and other far flung and truly remote areas like those.
But for the rest...nope. Time for them to go. If you or anyone reading this is in a position of authority in your little volunteer enclave, your first and foremost job should be exploring the possibility of bringing a professional service to your location. This doesn't neccasarily mean that your little squad or group or rickey rescue combine will cease to exist (though that may happen), just that your role, at minimum, will diminish.
And you know what? If you are really doing this for altruistic reasons...you should be ok with that.
Of course, if you are doing this for personal gain, be it socially, emotionally, or because you just want to be the "hero" you probably don't want to even consider that...
