One of the arguments for being very wary of dicey corporate practices overseas is that however much executives may argue that they are simply "doing as the Romans do," at some point those same executives will be returning home. They won't emerge from a magic shower that washes away their questionable foreign conduct. Those loose ethical attitudes may linger.
I find a similar problem with what is currently going on at many college campuses. Students who have shown an eagerness to suppress free speech are future teachers, HR officers, lawyers, and judges.
As with the business executives, we should not assume that they will go through a transformation. The number who do not may seriously affect the future of our society.
