Finally, someone knows the history and common sense.

The income tax history is really short. Even in US, the income tax was not significant until recent 50-70years. https://en.wikipedia.org/wiki/File:Federal,_State,_and_Local...

The China economy is behind US probably 20-30 years. Its GDP is large because its population is huge.

Why the Economist publishes this kind of low-level article?

Based on your graph the income tax became significant in 1943, which was 75 years ago. It was significant in France 30 years before that and in Germany and the UK 100 years before that.

This is actually pretty old and much earlier in development than what China is at right now.
