Yep, but think about it, it's not that bad. You arn't just paying for the 15-30 min you are in that ambulance, ambulance crews have to be on duty 24/7/365 even if there are no calls. It cost a lot of money to pay people to sit around and wait for something to happen. Than factor in the people that don't have insurance and don't pay there bills but use the system about every other day, than gas (ambulances get about 8mpg). It just adds up. Even at $1600 per ride (and that is in town, add $16/mile for out of town) most privet companies are struggeling to make ends meet, even paying there medics $9/hr with no benfits....
When I worked as a flight medic out average bill was just over $10,000 for a 1hr (total flight time) flight.
