15 years ago, there were nearly twice as many people living in extreme poverty. The world is changing very rapidly. I lent the book to friends to read so I can only paraphrase from memory, but what Hans Rosling wrote in Factfulness is that he went back 20 years later to the same place in India, showing them pictures of how it was there 20 years ago and the huge improvements that were made, the people flat out didn't believe it. "Sure it was worse 20 years ago, but it was never that bad" was the people's response. Romania is an example of a country that has developed a lot in the past few decades. I'm inclined to think that people can now afford AC, rather than that it's necessary. It's really nice having a cool place to work and sleep in, it really improves the quality of life, so when people can buy one, they would. I don't know about the historical price of ACs when corrected for inflation, but it almost certainly didn't go up, and Romania doesn't have the temperatures they have near the equator. Those few degrees due to climate change is probably not the reason why suddenly a lot of people decided to buy one.
