I think the method behind all the construction you saw was the same one driving China to export its goods at any cost, including lending money in any amount. The massive cohort of young, post-cultural revolution Chinese of job-age need to be employed, otherwise China becomes ungovernable. I believe the prospect of such a large number of Chinese in that class without a paycheck frightens Chinas leaders far more than any weapon our military possesses.
Very good point, PUGACHEV.
And if what you say is correct, then the new pressure from the trade war will cause a big crisis. Hopefully the Chinese will relent and allow true capitalism/free markets to come in and save the day.
May cause a new revolution, however.
