The soap which inspired my ire is actually Dial, but the curved, purportedly ergonomic and palm-fitting shape is shared by a number of commercial bar soaps today.

And speaking of paying for air, did you know there's a legal limit to the percentage of non-functional air fill that can be used in packaging? The McCormick spice company was sued and fined a while back because they changed the weight of black pepper per can from four ounces to three ounces without reducing the size of the can. The amount of dead air exceeded the legal limit. So, they were forced to change the can size. But did they reduce it by 25%, as logic would dictate? No way! They reduced it by as little as they possibly could and still be within the law.

By the way, the air in potato chip bags does not fall under the same regulation. It is considered functional air since it helps protect the bag from being crushed.

Also by the way, I'm sure this particular regulation is one the Trumpers would love to do away with. Make America Great Again by giving free-market capitalists free rein to charge exorbitant prices for as little actual product and as much empty space as possible! It'll be fantastic for the American economy! Really yuge! Just like the air-filled boxes it'll be packaged in.
