Photographer seems like an easy job. You get a camera - hell, we all have one on our phones - and you point and shoot. I'm sorry to burst your bubble, but it's not quite that easy though it will earn you some good money. The difference between a simple photographer (no disrespect there) and a photojournalist is that a photojournalist's job is to record specific historical events, versus recording moments from a wedding. The world at large could care less about your wedding, but the world at large does care about active wars or crisis.
For that reason, being a photojournalist can be very dangerous if you are tasked with taking pictures in a dangerous area, but risk equals reward. If you're a good photojournalist in a war zone, your salary will be plenty high. Even if you're not doing big-bucks photojournalism shoots, there are other ways to ensure you make your six figures each year.
