With their slow print speed, those cheaper tank inkjets are maybe usable for mostly paperless offices, or a home user that likes to print more often. You’d have to print at least one or two color pages per month to keep the jets clean.

As always, most consumers ignore the maintenance costs and buy the option advertised with the lowest price tag.

There are some inkjet options that do not follow that pricing model. The printers with an ink tank (epson ecotank, canon megatank, …) with ink for 3000 pages start at about $150, but are probably slower than the laser.
