We used to buy half gallons and gallons of ice cream. Brands started selling 60 or 62 ounces instead of 64. Over the years, it’s gotten to where some brands sell 48 ounces - three pints - instead of 64.
Breakfast cereals have had similar shrinking sizes.
Price-conscious shoppers still buy the smaller thing if it's cheaper per oz (and only if the stores show the price per oz on the shelf), but most people just get the bigger size because that's how much they want to consume, and they can't really tell that the 15% increase in size does not equate to 19% increase in cost.
Many stores would stock the family size separate from the regular size so the shoppers couldnt easily compare price per oz.
Eventually the family size just becomes the regular size, but now at the higher price. Then the shrinking happens again.
Legal requirement that they do in the UK (though in metric units), so it's £/L and £/Kg (or for smaller items per 100g and then some nuance on unit prices for things not sold by weight/volume).
It does make their shenanigans with multipacks and such way more obvious by design.
> The PMO also requires traders, where applicable, to display the ‘unit price’ – which is the price which would be charged for the relevant unit of the goods, depending upon how the goods are sold. Unit pricing can be a useful tool for consumers. It allows consumers to compare the price and value of similar products. This can be helpful when making a decision between similar products that are sold in different sizes or quantities.

Or another being "Made in USA", where Usa was a city in Korea.
Which as a highlander I don’t see the need for - Japanese whiskey is quite able to stand in its own and hold its own.
This tricks don't work any more.

It could be 99% filler and not be a lie.
There is no evidence that McDonalds has included any filler in their burgers at all (at least in recent history). See the link in the cousin-comment for more information on what has been claimed and what has been proven (so far): https://news.ycombinator.com/item?id=49247943
But the claim isn't about "the beef portion". If what you say is true it would give a competitor the chance to say "McD's burgers are 100% unhealthy fat" because the unhealthy fat portion is 100% unhealthy fat.

I doubt it. Not sure about the US but in Europe there are laws that tell you how much or how little of something you can have before you advertise that thing. For example you can't say "now with less sugar" if you reduced the quantity of sugar by 0.001g. And you can't call it "olive oil" if it has 2% olive oil.
Which is still way too lax. It should only be called olive oil when it's 100% olive oil. You can pick some other name like "olive oil based" or "unholy mixture of the cheapest gutter oils we could find" which clearly indicates that what you are selling is in fact a combination of oils.
For olive oil you can find the details here [2]. As above, there's no such thing as "the olive oil part was olive oil". The label is for the product.
The US probably has something similar, even if watered down.
