That's why when nobody wanted vhs anymore they just kept making them at the exact same rate for less and less money. They're still producing billions of vhs players every year and selling them at huge losses because wikipedia said something about supply and demand. You've cracked the code, you're morally in the clear now, you found the magic words that absolve you of all personal responsibility. Hoorayyyyyyyy.
"influences" is a pretty weasley word. show me a formula that actually (as in, verifiably) predicts how "demand" (a pretty weasley word itself) influences supply (probably the only concept for which we will be able to produce quantifiable numbers)
can you see how your want is not quantifiable? how much did you want a hamburder? could you have wanted it less? would that have decreased the supply? this is pure storytelling.
a moment of introspection here will show you that, in fact, this is about as close to the truth as you're ever going to get. all economic theory is storytelling. you happen to like some particular stories better than others, and so you choose to believe them (and even repeat them as though tehy are true). but they are not True in an objective sense. there is no scientific experiment that can be constructed to test these claims which would satisfy the skepticism of a critical rationalist inquiry.
that's fine. i believe (or act like i believe) lots of stories that i can't prove the truth of, which are actually unprovable. we all do. just don't try to pretend it's science.
