I remember the 90s when my family was poor in a middle income country. Mailing internationally was a huge barrier, we didn’t even think about it as an option. It’s 2 dollars now, but still, there are a few 10 or 100 millions people to whom that’s too much. And of course, there is no post service everywhere in the world.
