An acquaintance, well connected to the Chinese community, says it is much worse. There is a large population of young males that migrate to cities like Shanghai for work. They are now unemployed squatters in those “empty” 50-story luxury buildings.
The problem comes when the government “finds” something for them to do - like invade a neighbor.
The young, male population in China is definitely a ticking time-bomb.
Gertz in “The China Threat” points out that when growing nations reach a certain percentage of males to females (more males than females) the governments don’t have much choice but to send those “extra” males off to war. If they don’t, they remain single and often become problems internally.
