Don't underestimate a lot of these professions. In general, I think it's a great thing that the Chinese society values building real stuff over having the best and brightest working for parasite professions like lawyers and private equities. They've certainly made a lot of progress in every aspect of manufacturing. But ask yourself a question, why is China's soft power so much weaker than America's? There are real value in a lot of these professions that bring other aspects like entertainment to people's lives. People that produce software that everyone use brings a lot to a country's influence around the world. Similarly, a country's artists bring soft power. How is it that South Korea has BTS and produced "Parasite" and "Squid Games" while China has produced no similar culture hit.
While having too many investment bankers is not good, having a vibrant and transparent banking industry allows America to retain its dominance over the world through US dollars. Can you imagine America without having the world's reserve currency?
So while having technological prowess gives a country power. So do banking/finance, software industry and pop culture in different ways.
