Can you also make a defense for racism using the same parameters as you want the aforementioned points reasoned out with? Sometimes, logic needs to be manufactured hand-in-hand with what's morally right. The transition from slavery, to equality wasn't easy, and neither was it done overnight.

I'm not saying a borderless planet would work out; at least not anytime soon. But we should at least be working towards it.

We know that AI could go bizzarlly wrong, but we still work towards achieving better results everyday.

The point I'm making is that not everyone agrees with you about what's morally right. In fact, most people in the US, at least, do not. If you want to effectively advance your cause, it is worth finding an argument for your claims which does not rely on moral precepts your interlocutor may not share.

As a side note, likening the existence of national borders to the institution of slavery is probably not such an argument.

If you take it with an open mind, you'll see that my intention is not to liken them, but to demonstrate that not every cause has an inherent, intrinsic argument.

It's not a surprise to me that it's most people in the US that are against the idea of this, because they fear that instead of the datum of other countries moving up, that of USA will go down. This insecurity always annoys me. But take everything I say with a grain of salt because I do not consider myself patriotic whatsoever, and in that sense, my thoughts are in the opposite direction as those of Americans, who, through personal observation are the most patriotic people I've come across.

I don't believe any answer to a "what ought we do..." question can cohere without agreeing to a shared moral framework. The answer to the question will always assume you want to maximize something(s) and choosing among those competing somethings will always be a values judgment.

I really hope you're wrong.

Well what would the logical alternative be? If I argue that someone should support a policy because it serves their self interest, that presumes a moral framework. If I argue they should support it for the greater good, that assumes a moral framework. And so on. I don't think it's a question of looking really hard for the right argument, such an argument is logically precluded.

And it seems to me that most people's framework tends to fall somewhere between the two. People actually aim to maximize some function that depends on both self-interest AND the greater good. The weighting between the two varies between individuals, based on numerous other variables, but very few people are 100% one way or the other (Mother Teresa vs a sociopath). So ISTM now that the goal isn't to convince people to follow a particular moral framework, but rather to attempt to influence the variables that already steer people toward one or another. One of those is exposure. There's that Mark Twain quote, "Travel is fatal to prejudice, bigotry, and narrow-mindedness..." Another, as discussed above, is financial well-being. The more comfortable one is personally, the easier it is to consider the plight of others. There are certainly others.

I agree with you that while there are some appeals to self-interest that support a goal of equality, fundamentally it is an issue of morality. And I agree with you that you can't logic someone from one moral framework to another. But I would add that almost everyone does have some amount of 'maximize the greater good' built into their moral framework already, so the only logical way to work toward this is to focus on the variables that will add weight to that side of the equation.
