That’s the most foolish thing I’ve read in a long time.
When I was growing up, I was a bit stubborn regarding use of soap and deodorant: I pretty much refused to use anything but water to shower, and never used deodorant (or any other topical substance, for that matter).
That approach worked just great, until I hit puberty... Trust me, if you think nobody needs deodorant just as long as you don’t use soap (or some other such nonsense), I am the living proof of just how extremely far from the truth you are.
Of course, many people out there will never need deodorant (genetics play a large part here, according to some studies I’ve read). There may even be some microbiological technology we can find to cure body odor in alternate ways. But to assume that deodorant is a universally needless product (in favor of not using soap) is incredibly naive, or nearsighted.
I’ll save responding to your random derision of capitalism for another debate.
