> don't we grow tolerant to pleasures

For some, the tolerance doesn't cause them disinterest but rather a drive to go further. Can they get an even _saltier_ chip? Or rather more flavorful with increasingly exotic condiments. Or one bowl no longer does it, maybe 2 will do.

You can see this in American supermarkets on the snack aisles. You see variants of the same products from plain/traditional, to novelty flavor, to 5x extra novelty flavor. It isn't just marketing or just the normal distribution of individual preferences. I think it is a hedonistic ratchet. You see it in the level of nuances specialists take to any field or hobby the deeper on delves. The craft beer connoisseurs to who keep wanting more hops in their IPAs are a good example too.
