> I don't understand the whole "If you behave logically as a business we hate you" sentiment.
I agree with this. Businesses will work to maximize their benefits under a system (just like most humans will).
> It is the job of a business to make money, the most money possible, at all costs. That is its single purpose existing.
I think that is the market-pressure for what businesses should do and the single goal of many investors. But I am not sure convinced that is truly the single purpose of a business.
