Are you aware of the difference between absolute and relative poverty?
I mean, really, take a step back and consider these two possibilities:
a) Thousands of researchers have researched the topic for decades, and no one ever considered it problematic to directly compare the poverty in Congo and the US using the same metric. But finally, after als these decades, during a few seconds of flying over a blog link, commenter
fuzz4lyfe on hn finds the error and renders decades of research obsolete.
b) You err.
What is more probable?
