The US economical strategy is short-term oriented, China is long-term oriented. That's one. The US do not see gain beyond 20/30 years and it's sight limit itself to 2/5 years.
American politicians, and brass at the white house, only think mostly, is that gonna make us some money ? The problem is, let's say, there is 100 fish in a lake, you don't just come and let a corporation who is apatrid fish the 100 fishes and sell them on the market.
The CEO and shareholders have made enough to do hookers and cocaine for the rest of their lifes, still, you end up with a crisis. There is no fishes anymore in the lake.
You need to make laws and regulations, do not fish more than 60% of the fishes, and never fish fishes when they are pregnants, in that period, let them lay eggs, and with big nest, who do not catch baby fishes. You are sustainable for 50/100 years with no problem.
This is the mindset of the americans. Another example would be, an american business man, owns 10 lands. He will build 10 buildings, residential complexes with a lot of appartments for money gain. But he would have made more money if he build 7 buildings, and built one parking, and one green park, and one pharmacy/drug store/food store/groceries store, because with the external positivities they would bring, the price of real estate would have increased more with 7 buildings and nearby infrastructures than with just 10 buildings.
China will beat the US because it is more long term oriented and also more wise.
Everything China has, the US is able to do it. With no exception. If you ask an US official to build huge infrastructures that could benefit on paper and in reality the country, or the common man or both, he would say, hahahaha why would we do that ? That does not generate money !
Commodification to the extreme of everything do not benefit the country but only apatrid short sighted corporations. For example, developing the US will not be a bad thing, not just for social/environmental gain but simply for economical gain.
Huge infrastructures will bring back many positive externalities, that will increase tourism for instance, and thus will be able to generate more money and of course much more.
China is very likely to surpass the US in technology, architecture, and AI. The average chinese worker is more patriotic and collectivist than the average american worker who is apatrid and more individualist. That also count a lot.
Another problem in the US, is that US and western corporations will overprice their services. A road that on paper would cost 10 dollars would cost 40 or 60 dollars. Which on the long run do not help building infrastructures at a high speed rates and at a large scale.
