And high volume. Believe it or not, inkjets have lower cost per page than lasers. Especially with the newer tank-based printers, but they were already cheaper before those.
The trick is that you have to use up all the ink before it dries. Printing out a few odd documents per year won't do that. That's most people's use case, and lasers are superior for that because toner doesn't dry out.
There are a few odd niches for inkjets, but he sub-$100 printer market should die in a fire. If you can't afford a somewhat more expensive printer, then you're not going to be able to afford the ink.
