Geldmacherei or why so little ink for so much money?

I use for 15 years Canon and HP printers. For about 2 years, I note amazed that fewer and fewer printed materials with the cartridges can be printed when the printer cartridges have become much more expensive.
Even from the so-called, even more expensive "XL" cartridge extract just over from the normal.
Even years ago about 8 I have with the Canon cartridges (well, there were older printer models) each almost twice as much (black and white) can print texts than it is today.
I shudder when I umrechne the amount of ink in euros - what a luxury! Well, the price of salt was just as high in the early Middle Ages.
It would surely something more ink at the same price without that Canon and HP would poorer. (Oh, the jobs would be but then again in danger!)
Printer's for a knockdown price - with the cartridge, the coal is apparently done.
Annoying also the opening of the (Anti-Burglar?) Packaging. With an ordinary pair of scissors that's difficult - and I am always a pruner. In short: A little ink for a lot of money in a burglar-proof packaging.
Personally, I'm going to whistle on the guarantee and let my refill ink cartridges in cheap shop - because if the printer is broken, a new cost not much.
