Not to ruin all the excitement, but as a southern california EMT, you can expect to work at a private ambulance company that goes to the hospital and brings patients back home when they could have taken a taxi, and than medicare gets billed for the expensive and needless ambulance ride, which further bankrupts the system.
You will be doing discharges. Bringing people back to their nursing home after they were hospitalized for UTI and sepsis.
The fire departments own EMS and have a death grip on it to justify their existence. But do not let this get you down. Its a tuff world for an EMT in socal, but stick with it and get your hours for paramedic school. I survived and so can you.
