Capitalism cannot avoid the economic crisis because of its own defects. The US stock market economic crisis in 1929 and the US financial tsunami in 2008. In fact, the current US system is not a capitalist system, but a private system strictly regulated by the government.
The advantage of state-owned enterprises is that railways and roads can be established in remote areas rather than being criticized. If the system is based on the absolute capitalist system, Tibet should not build railways at all. Even highways should not be built. Because it is not economical, that is why US has no high spped railways even in California,no need and really not economical.
State-owned enterprises also have many drawbacks. Even in China, it is accused
China is respected for its private high-tech enterprise such as Huawei, as well as Alibaba, Tencent, Haier, Hisense, Gree and so on.
What does this have to do with the US becoming a developed country? You are going on a tangent.
By oppressing black slaves, the United States gained the accumulation of primitive capital that was impossible for others.
Hiring 100 industrial workers and buying 100 black slaves who can have children is not economically comparable.
Just like building a company, getting raw materials for free and getting raw materials at market prices, there is no way to compete fairly.
Aggression and colonization of other countries can freely access resources and markets (US British products are sold to colonies, tariffs are basically negligible)
In 1842, the Sino-British Treaty of Nanjing, the United Kingdom required the Chinese government to obtain British consent on tariffs.
Sounds similar to Trump's unequal treaty? No?
