328 million/7.9 billion ~= 4.15% The poorest Americans are definitely much poorer than the poorest western europeans [1]. Western Europe has 196 million people (about 2.4% of the world population) [2]. I'd estimate that 10% of the world population (790 million people) has a comfortable modern middle class life. It's just an intuition. Northen Europe as 106 million people.
