How crunchy is too crunchy?

I am one of those sensitive people who can't stand to listen to others eat, chew gum or swallow. That being said, I don't understand why companies keep making chips crunchier and crunchier to the point where I can hear someone eating them from a mile away. I can't believe that there is exponentially more enjoyment to eating something that is so crispy that you could chip a tooth on it as opposed to a traditional chip. Is it the taste? And isn't chewing something that thick and crunchy more work? Where is the enjoyment in that? I think all of those kettle chip/traditional corn chip manufacturers just need to cool it. Have some mercy on my ears--please!
