Eh, shrinkflation is a number of small things like 90% pork to 89% pork. Do that 5-10 times, 1-2% at a time - and now you're at 75% pork.
26% marinated chicken to 14% cooked marinated chicken - what makes you think the lost fat made it into the meal, and wasn't skimmed off and sold off to (for example) a broth company, or a rendering plant?
Maybe it was. If they could figure out how to make money off it though, chances are it wasn't.
Also, how would you know it wasn’t really 20% chicken cooked down to 14%?
It's a good way to lose actual calories and nutrients while thinking you're not losing anything. Which is also either shitflation or shrinkflation, depending on how you count it.
Totally agree on deflation, etc. though. That could also be from switching to reasonable quality ingredients to total crap ingredients that technically can be listed as the same thing on the label.
The challenge in general is it's the economy wide equivalent of shaving silver dollars - lots of small, invisible losses done by potentially many individuals that eventually add up to real visible differences and economy wide losses. In a way it's really hard to figure out who actually stole things.
