I haven’t thought about this enough to come to a conclusion personally, but the argument phrased non-horribly would be:
“I would be ambivalent between living 1 year in a first world country, then dying, and living 3 years in a 3rd world country, then dying. If I treat everyone the same as myself, then I should be ambivalent between 3 years of life for someone in the first world and 1 year for someone in the third world.”
However, one huge problem with this is you’re taking your own morality and imposing it on others.
ETA: Re-reading the original post, it doesn’t look like it’s saying that first world is worth 3 times third world. It’s saying that assume that you don’t value your personal life more than 3x a random other person’s, which is an entirely different argument.
