When will consumers wake up to the shrinking food package + inflation scam?

[enlightenment]

72. I do understand the difficulty of translating

volume to weight (designed a couple of cookbooks that needed to translate to both US and UK measurement).
I discovered that, when I am very frustrated by this, the Internet is a life-saver, though I suppose it depends on how much time you have to devote to the research.

For example: this website has a handy little chart for that unique #1, #2 can issue -- http://www.ellenskitchen.com/pantry/cansize.html
She does discuss changes over time to a degree, but more importantly, lists the original sizes and comparative volume.

Another trick I've used (if you have time and don't mind the slog) is to search for 'retro' food ads. Search for the medium or large images and they are often big enough that you can literally read the package on the advert and figure out how much it held before the downsizing/uppricing trend hit.
