Photojournalism is only worth it if you can land a staff photographer gig, otherwise it's really shit work for little pay, and high competition.>>3763574
You can also do product photography at $10-$15 per image. You get a few clients steady each month that put out new products (clothing, accessories, etc). Depending on how many clients you wrangle it can quickly turn into a steady income. Basic Amazon-style shots are incredibly easy to do and churn out, so if you have a client that wants 25 or so items photographed, each with 3 images, that's $750 a month. Get four clients and you're making a comfortable middle class salary. It's actually easier said than done, but once you're in, you're in.
Product shots with models can get pretty good cash too—somewhere around $200 per image at the low end, $6000 on the high end. Very competitive though.
You need to be a good businessman first—the photo part, once you're confident and consistent (easy to reach with product shots) then you free up a lot of time do cooler stuff, like commercial lifestyle shit for magazines or whatever.
