The CEO's of these multi billion dollar companies are tasked with increasing share holder value, increasing revenues and profit margins. At all cost.
We are looked at as the stupid consumer who's not smart enough to notice the product is tiny now as compared to years ago. 1 out of 5,000 consumers even notice a change. We just accept the triple price increase. 1. Shrink it. 2. Raise the price. 3. Change the formula. Wonderful for margins/revenue/costs. And a 4th, with inflation, throw an extra stupid high price increase for good measure. With no basis for such increase. 5th, pull this silly, arbitrary measure garbage. Give the consumer a massive cup to use. Put in a drop of detergent for that "regular" load. Pull all the above, get rewarded with stock options and a huge performance bonus. Rinse and repeat.

How do we get the other 4,999 customers to notice? We get enough to notice and boycott the item, then we hit the companies on the bottom line. Some grocery stores were boycotting Pepsi products due to insane price increases.
