The title is a bit of an exaggeration.
Why do corporations change shampoo and toothbrushes so often? I’ll go through 10 different shampoos and toothbrushes, then find ones I like. I’ll probably be able to purchase them again a few times before the ones I like are no longer available.
What are the forces driving manufacturer’s to change their basic wares so often? Besides Wall St. greed, that is?
Trader Joe’s tooth brushes have been good and consistent for a decade at least now. They have a funky bend and it works great.
