People vote with their dollars against their own best interest all the time - typical examples include narcotics (don't take that comparison for more than I meant it to be, it's just an example of how people buy "fun stuff" that they objectively should not) and in-app purchases in cheesy mobile games. Profit motive can only guide profit seeking companies to serve people's happiness to the extent that people can exert self control, and that doesn't work very well.

You are confusing happiness with something else. The problem of language dominates these conversations, and by not being careful you risk being refuted by Plato's Socrates 2500 years ago in the Meno among other things.

You could substitute almost any definition of happiness in my comment and the argument would still work.

I don't remember anything Plato said refuting what the GP said.
