From a humanist angle, those buildings are outrageous monstrosities and monuments to human egos. However, they were built from wealth generation that probably gave farmers in paddy fields the opportunity to be elevated out of relative poverty to positions where they could gain an education and likely some are now right here with us on HN.
Likely it was all paid for by your average WalMart / Apple / Amazon shopper.
A deeper question is if we feel this is money well spent, and skyscrapers as legacies certainly didn't start in China and are quite prevalent in the West as well.
Taxing the hell out of frivolous luxury goods might be a jolly good start but dunno if that's going to fly anytime soon because even that is a subjective call at best.
Boo, tricky stuff :/
