To be very fair, Chinese companies are also pursing quarterly profits. They're just better at scaling things up and down very fast because of immense supply chain options.
Chinese companies are simply not as beholden to shareholders - the stock market really doesn’t dominate the country’s financial landscape as it does in the US
> immense supply chain options.
so this begs the question - why isn't the west's own supply chain options as immense? My unresearched answer is that the gov't policies of the west doesn't induce it, while china's gov't does (which includes targeted subsidies, tax incentives and state driven finances).
The "hidden" cost is that the workers in this supply chain isn't as well paid and isn't as powerful as the workers from the west (there's no unions in china for example).
