>The Veil of Ignorance, anyone? Even invented by an American.

As long as we're talking about the veil of ignorance, let's also consider the "veil of birth country ignorance". What if you were born in Africa?

From that perspective, one of the most altruistic things a developed country can do, arguably, is increase its rate of immigration from developing countries.

Of course, if you do that, your average citizen gets poorer ;-)

That’s not exactly the only condition. You also have to not frick with other countries. Like e.g. France’s Neocolonialism.

There are other examples.
