That's my fear as well, although I've seen a decline in the market over the past few years. After the banner ad crash of '08 it became harder for indie bloggers to make a living. And another problem I see these days is that not only are banner ads paying badly, but money has flooded into the field to back winner-takes-all ventures like Vox or Buzzfeed. So it's hard for the little guy to even get pizza money at this point.
