No, they do not. And even if they “claimed”, what of it? A claim is just a claim. Here is a local ordinance for you: “it is illegal to feed someone else’s parking meter”. I am not kidding, this ordinance exists. So there are laws which prohibit helping someone else. What kind of morality would that be?
Now I’m really getting confused. You seem to be saying that there is some true morality and you can judge true moral claims and others can not. We cant rely on the traditional understanding of morality which involves the rather simple concept that some things are right and some things wrong.
Regarding this parking law I would disagree with it and think it is revenue generating. But there is a moral argument for it. The lack of awareness of this reasoning can be understood by your misunderstanding of the Golden Rule. Your misunderstanding is common, even among Christians. But it leads to many great errors in thinking.
Besides the two versions of the golden rule are not specific, they are pretty vague. The direct one simply says: “be nice to others”, the inverted one one says: “don’t be mean to others”. So, even if “all” societies adhere to them, the rule is so generic that it is next to meaningless. They must be “translated” to specifics before they can be addressed in a meaningful fashion.
This is a simple and wrong understanding of the rule. If it were actually this it would be unremarkable and a rather worthless rule. The moral claim of the Golden Rule (GR) is so much more than what you make it out to be.
The GR says to do unto other as you would have done unto you. But what is unsaid, but so and must be, is that the analysis must be done as if all parties are acting morally.
This important attribute is easily demonstrated. If the GR meant the simple idea then a criminal when caught should be let free because the legal authorities could say to themselves ‘if I were a criminal I’d want to be saved from my punishment’. Such a rule would then become a tyranny since criminals would avoid punishment and thus actually be encouraged to crime.
What should occur is the legal authorities should say ‘if I were a moral criminal then how should I be treated’. And the answer would be to suffer reasonable punishment for my misdeeds. This means a punishment that is not too severe or too lenient. Of course this is always dependent on the circumstances because all morality, in any system, is dependent on the circumstances. What punishment is just right can be hard to determine, but that is the goal.
When the GR is claimed to be just being nice and not mean it loses its potency. And your mind ignores the rather important concept of justice.
This relates to your parking meter law. The law has every right to say that you can not help someone to avoid the just punishment for violating the law. In fact throughout the law there is a concept that it is wrong to help people get away with a crime. And if the GR is in force then the person who violated the law and stayed too long at a metered space should realize that they were in violation and accept the punishment for this because that is what the moral person would do.
This is how this law is justified and it has a moral argument. Whether or not this law is good in a particular case depends on the circumstances. If there was a person who fed meters on a block all day thus allowing people who parked there early in the morning to not pay the true cost of what they take and thus keep others from being able to use the spaces then this act would be wrong.
Laws have nothing to do with morals. Whatever some people (lawmakers) wish to put into laws and which pass judicical muster will become laws. Sure, the lawmakers will assert “something”. But they do not reflect the “prevailing opinion” in every case. Mostly they are elected because the other side is even less palatable. In the US there are laws against importing non-US-approved drugs for personal use even if those drugs might save the person’s life, and even if those drugs are already approved in the originating country (Canada or Europe, for example).
I agree that many, maybe even most, laws are passed for rent seeking purposes. But they are always presented as good using a moral argument. And it must be pretty convincing because people keep electing politicians, who want to pass laws to cover most human activity (with the sole exception of abortion and formerly immoral sex acts), based on the good things these laws will do. If people weren’t convinced by such flimsy arguments then they would not elect these politicians in the first place. So you run into a problem with your ‘prevailing opinion’ argument because democracy gives us a clear idea of prevailing opinion.
Most people want to put people in jail for growing, selling, or using drugs that are not made by a corporation and prescribed by a doctor (who in essence is taking his cut of the action). Most people want to disallow a business from hiring whoever it wills or engaging in trade with whomever it wills. I disagree with these laws but the people who dont, who are the majority, believe these laws describe right behavior and not conforming to them is doing wrong or immoral.
