I have no problem with the comparison. DRC, Pakistan and Serbia are moderately good on net, with most having a good life and a minority being absolutely screwed. The idea that their average level of quality isn't similar to America's after adjusting for purchasing power is an insult to the many people living in them who are striving for good with a remarkable degree of success.
There are a great many academic data sources justifying this in all cases but if you still disfavour them and would be swayed by an informal documentary instead, I can recommend the Miracle of Pakistani Tekken as the best short-form documentary on how their people are as well-meaning as you or I:
[edit] I mixed up the DRC with it's northern neighbour, the RoC. The RoC is an adequate place but the DRC is a hellhole that doesn't belong on this list.
You’ve got to be kidding. The DRC is an unfree authoritarian state and one of the poorest countries in the world to boot. It’s in a completely different tier from Serbia.
