Survival bias get in the way. The morality you refer to exists, it just doesn’t survive long enough to notice. So yes, you do something ostensibly immoral but legal for some advantage, that advantage allows you to economically out compete your more moral neighbor, who winds up insolvent eventually. If morality isn’t encoded in law and their is an economic advantage to being immoral but legal, then that’s what you will ultimately wind up with, because the moral actors will simply die off.
