interesting article but I personally disagree. Chinese leadership is based on engineers while the US nowadays is made up of uneducated idiots.
This, I feel, is a talking point that has outlived its usefulness.
Let's have a look at the education background of the Standing Committee of the 20th Politiburo (undergraduate only):
Xi Jinping - went to Tsinghua as a Worker-Peasant-Soldier Student, studied chemical engineering
Li Qiang - Ningbo Branch of Zhejiang Agricultural University - agricultural mechanisation
Zhao Leji - went to Peking University as a Worker-Peasant-Soldier Student, studied philosophy
Wang Huning - Shanghai Normal University, studied French
Cai Qi - Fujian Normal University, Political Econmics
Ding Xuexiang - Northeast Heavy Machinery Institute, engineering
Li Xi - Northwest Normal University, Chinese Language and Literature
So it's a even mix between people who studied science/engineering vs humanities. Also I have to note that higher education in China during the Cultural Revolution was not great, so you'd have to put an asterisk on some members who did study back then.
The myth of 'engineer-technocrats' as leaders of China was really a thing only for the Hu-Wen era - ie 16th and 17th Politiburo era (2002 - 2012), when both Hu Jintao and Wen Jiabao were trained as hydrologist and geologist respectively. It made sense in context - China was in the midst of massive urbanisation and infrastructure building. But as China's economy and growth driver transitions away from infrastructure building, we will see a mix of qualities in the top leadership team.
