I understand that logic, but as a counter, my time and frustration are worth something to me. I've actually owned both a Vitamix and a Ninja, and start basically every morning with a blended combo of protein/fruits/frozen greens, so it's a great example. A lot of the premium for me in a better product isn't just lasting longer and not throwing things away constantly, it's avoiding the frustration of using worse tools.

The vitamix has been thoughtless for me in 6 years of daily use other than sharpening the blade every so often and replacing the bearing for the blade once (both easily done by me at home). I wake up bleary eyed, throw my stuff in there, and let it eat for a minute while I get my coffee going. The ninja on the other hand did a consistently worse job, required me to remove it and shake the contents of the blender, and then randomly fried itself one day in a way that I had no chance at fixing and scrambled my breakfast plans for multiple days. What's daily frustration worth for a half decade of my life? At least to me, a lot more than the premium to get the better tool.
