Wrong I part time with a rural service with maybe 250 runs a year. EMS is supported by billing transports and non-transports. The deficit is covered by about $60 per year per homeowner, aprox 900 homes. This service pays 4 full time with benefits medics, and has about 4 regular part timers and 2 or 3 of us that will try and cover a couple of shifts a month for them. Do they pay good, no not really, basics start at $9 hour plus overtime. So nobodys getting rich, but they're not holding other services back by being vollys. I hear it all the time at my primary service(about 700 calls a year and hospital is 90 miles away) , WHY CAN"T WE BE A VOLLY DEPT LIKE SO AN SO? So yes vollys hurt us when we try for pay raises, when we try and get more people on staff, when we try and better serve the people the coverage they deserve based on the taxes they already pay.
That calculator you used is in my honest opinion probably controlled by communitys that are trying to avoid people being paid for doing the job, regardless of what is claimed.
Not trying to argue with you but I to was a volly and thought the same crap you do. I started looking at the money the city and county wasted on holiday decorations, throwing partys and festivals, etc. That alone could have at least paid half of what it would cost to go payed service, the rest could have been covered by the billing. So I say if it looks like crap, smells like crap, it's crap. Or to be more polite if it quacks like a duck, waddles like a duck, looks like a duck, its a duck. Sorry, I feel strongly about this for 2 reasons Myself and my family suffer because of vollys hurting pay, and because it makes me mad that I was stupid enough to think the way I used to.
Have a nice day. Rantings of a tired old man will continue later.
