That's from their companies refusal to adapt which is what ended up killing them, since in countries where they did successfully adapt in the East trains are fast and affordable enough to seriously disrupt even airline routes.
Only because they get massive subsidies (Europe), made their competition illegal (France), and/or have no competition (China).
Focusing on China, they have barely any airports relative to their population because the CCP chose not to invest in them because they reserved most of the skies for military use.
86 million people live in the Pearl River Delta (one of the richest parts of China), yet they only have two real airports:
The red airports are Macau (one runway) and Hong Kong (three runways), both technically not in China.


Hong Kong is a major airport though.
The blue airports are Foshan Shadi and Huizhou Pingtan, both dual-purpose military airports with a single runway. Huizhou has four jetbridges, Foshan has none.


An airport Huizhou's size would be classed as a regional airport in the US and Foshan wouldn't even count as one. Cody, Wyoming (pop. 10k), has a nicer airport:
The only two real airports in the PRC part of the Pearl River Delta are Shenzen Bao'an and Guangzhou Baiyun (in green).

I believe the small terminal on the right in Guangzhou is the High Speed Rail terminal.
Hartsfield-Jackson in Atlanta is bigger than both of them combined despite Atlanta having 7% of the population. Now,
China is building another airport for the region, but even with it they'll still be way behind the US on a per-capita basis. The 50 Cent Army is extremely vocal about how China is a "world leader in High Speed Rail" because they know that they're far, far, behind the US when it comes to intracontinental travel.
American urbanists are useful idiots who take for granted how easy it is to get around both the country and its cities. They believe Chinese/EU propaganda about how far "behind" the US is compared to their countries, when in reality the US is way ahead of them.
