Depends upon what you mean by amoral or immoral. Biblically, we see Jesus throwing the money changers out of the Temple, although that seems to have a lot to do with defiling the house of the Lord. And throughout the bible, there are numerous passages that warn of the love of money, and even from Moses, laws against usury. But on the other hand, there is always talk about God awarding earthly goods for being good (Old Testament). It seems that, especially in the Old Testament, there is a conflict about business and wealth - being both good and bad. And then in the 18th century, you have a whole philosophy call Utilitarianism. To be honest, I don't think anyone, even today, truly buys the idea that business is amoral - except for people who use it as an excuse for immoral behavior so that they can make a profit.
