Not really. It's an entry-level job that pays poorly. Even paramedics with a two-year degree don't make jack squat. EMT-B can get you in the door for some hospital jobs like ER tech that pay better, but in EMS it's barely enough to live on as a single person. Making a living in the back of an ambulance is not unlike making a living as a musician -- it can be done, but it takes years of living in poverty and working awful schedules before you get a glimpse of a decent career. Long hours, low pay, and no benefits are pretty much standard.
If you have other reasons for wanting to get your EMT certification, then, by all means, go for it. If it's just a means to make some money for a year or two, it's not worth it. You can find jobs that pay the same or better that don't require all of that time, effort, and hassle.
