I would say however if you are managing to stay with a range of lifestyle you are probably gaining from new wealth even though it is not extra wealth which you are accumulating in a bank. You are generating new money and that is new wealth. Every year that 80K is new wealth, I am pretty sure that is how the definition is in this case.

A person in Sudan is averaging around $460 US a year, while in the US it is like $74K, and thus Americans are accumulating wealth at a higher percentage.

Also the comparative lifestyle in regards to goods and services are much different. While it might be more expensive to live in the US the lifestyle is dramatically different. Wealth doesn't always mean accumulation.
