@cicerone imposter,
Yes, but they are worked out over time, with effort. Moral codes develop in time with the social welfare of a society.
In the US, letting a man starve on the street is morally tolerated, and that is reflected in the welfare system of the nation. The state isn't legally obliged to provide someone with a place to live if they cannot do it by themselves. In Norway, it is not tolerated, it's considered immoral, which is reflected in the welfare system where the state is legally obligated to provide a home for those who cannot do it by themselves. Of course, that doesn't mean that there are no homeless people in Norway, merely that the moral code here holds that there should be none, so that is what we work towards.
The same welfare system provides us with free health care. Cancer might ruin your life, but it will not ruin your finances, as it might if you get it in the US without proper health insurance.
So, both of these respective cultures have a moral code that reflects the general mindset of those who live there. These "standarized moral codes" are negotiated socially with regard to the personal moral code of everyone who has a right to weigh in.
