Are business people inately amoral orduzthe profit motive trump all ethical concerns in their business studies

Nature or nurture!?.. ..are those who are attracted to business, deficient in their ethical make-up..before they ever get to business schools and universities...? ....or is their business education, devoid of any ethical considerations..and so ..generating amoral action/strategies, at the top of all businesses? ie: are they taught/encouraged to be amoral, by their course material?..or is it just that more amoral people are attracted into business than other line of work? and are they taught that the greed of shareholders,is "obviously"[!] to be put above any reponsibility to the wider community..and the wider world?
Answer
As a business person, i take offense when people question my own ethics solely for that reason. it demonstrates a pre-conceived prejudice that could have only be driven by sour grapes about those who have more than you. it also demonstrates that "the offended" possess more greed than those they condemn as "greedy" who are trying to make an honest profit.
