Not true. The article is not about living with the equivalent of $2 in USA, but a few African countries and values converted in dollars. A few years ago some colleagues of mine spent a month in rural, mainland China, trying to see how people live with a few dollars a day. While those people were poor, the numbers are very misleading when you convert in dollars.
No, you’re wrong. It’s not about converting what they earn to dollars using direct exchange rate, it’s about converting it to dollar’s purchasing power.
That is a direct conversion. Where is the purchasing power conversion?
