>>> Western business culture is primarily "profit is the end that justifies the means"
This is certainly not true as otherwise there weren't as many charitable funds sponsored by businesses and as many publicly useful things done by those.
>>> exploit any person, resource or environment to their|it's detriment
That is not true either, moreover - this is not true even if we accept your previous premise. There's nothing in making profit that mandates that it would be to the detriment of any person, resource or environment. Moreover, not ruining the resource supporting your business is certainly more conductive to the profit than ruining it, since it allows to extract profits for the longer period of time, so even from pure profit-driven approach you are wrong.
>>> Equality, helping those in poverty, cultural benefit, elimination of crime - none of these are Western business ideals; they're cultural constraints placed on businesses
Equality taken as equality of citizens before the law is certainly good for business, since inequality usually means inability to conduct certain profitable deals. E.g. when there were place "for white people only" in US, it meant profitable business involving non-white persons could not be conducted there. Crime is obviously bad for almost every business (maybe excluding security guard and alarm systems business).
>>> Now not all businesses are so immoral - but I'd say immorality is indicative of "Western business practices"
Since western business practices is nothing more but Western people conducting a set of voluntary transactions, you've just called the whole set of Western people inherently immoral. Not only this smacks of racism, it is certainly not matching the observable truth of Western people having a lot of morals guiding them.
>>> when those businesses get to exploit people and environments that aren't being monitored and aren't subject to legal protection that's when the abuses of the business ethic rear their head.
Oh, I see what you mean. Western people are immoral in general, but there is a tiny sliver of them - those that enact and enforce the "legal protection" - i.e. the government - that are the moral backbone of the Western society. As soon as the person joins the government, they become moral, and able to enact the protections derived from their freshly gained morality, and as soon as they leave the governmental aegis, they revert to their natural immoral state and only the "legal protections" keep them from running rampant exploiting people around them.
