Why doesn't the USA look like the largest economy in the world when I travel there? China's top cities look even more advanced than American.
Look at this photograph. Looks like a nice city eh? It is Kinshasa, capital of the POOREST country in the world, the “Democratic” Republic of the Congo. So when comparing countries, it might be best to compare how the poorest areas live rather than the richest areas. For example, if you drive through rural areas of the US, be it in the South, Midwest, or Southwest, you will notice almost universal paved roads, electricity, and indoor water and sanitation. Rural China? Not so much.
