> What an about the principle of fairness and people being treated equally?
Life is not fair from the moment of conception choosing which parents and location you are born to.
> If a business is only viable by extracting the most from every individual instead of finding a fair price, is it really better for society that business exists?
A buyer buying for the lowest price they can and the seller selling for the highest price they can is the definition of a fair price. Since supply and demand curves are constantly in flux, the fair price is also constantly in flux. Hence the practice of haggling with every vendor in old school markets/bazaars, even for daily vegetables.
