Otherwise known as shrinkflation. Selling a product for the same (or higher) price, but adding less of the product. By cutting small, barely noticeable portions out a little at a time, the company saves money in materials, but continues charging the same price. Basically, min-maxing profits.
When I lived in Germany for a couple years, I was surprised to learn that the large church in the center on my village was about 1,000 years old. This one building has been standing longer than America has been a country. Over 4x as long, too! European culture amazes me because there’s such a lengthy history, and so many things are much older than I’d imagine. American history is so short in comparison, and we’re more likely to tear down and build new and cheap than create a solid structure that will last for hundreds of years.
