China enjoys a trade surplus with almost every nation on earth. China thus enjoys huge surplus funds- in fact what to do with those funds IS a problem- they don't want to put more into US Treasuries. They are investing hugely in infrastructure - globally- belt and road- Chinese controlled trade route from Europe to China. Real estate in China has had some excesses but who had been hit with the bulk of the costs? Greedy naive western bankers- https://fortune.com/2024/02/08/evergrande-liquidation-99-percent-haircut-hedge-funds/ Never have free markets alone achieved lasting wealth- there has always been a substantial factor of good governance and strategy aligned with business interests and the military to achieve resource hegemony and trade dominance.

Yes the days of science engineering and productivity being prime drivers of western politics are sadly long since passed. In contrast in China the vast majority of the politburo are trained engineers.

In the West the most powerful engineers now are the financial engineers who work for the banks who in turn own most of the politicians. They add no value- they are simply parasitic rentseekers steadily undermining the competitive advantage the west once enjoyed.
