How many state-owned enterprises in the United States are among the top 500 enterprises in the world?

First, there are no state-owned enterprises in the United States. The United States does not allow any government unit to run for-profit enterprises to compete with the people for profits. The exception in Wei Yi is the United States Postal Service. That's because in the early days of exploring the country by horse, the border was too big, and no one could afford to organize and deliver cheap mail, so the government was responsible. Now it has become a burden for the government to lose money. Therefore, all institutions in the United States are private or listed companies. Even those who make airplanes, missiles, tanks and cannons, aircraft carriers and submarines are private companies. Another example is the national aeronautics and space administration, which is paid by the state, but it can't make a profit. The scientific research data it has obtained must be made public to the people. There are not only 500 Fortune 500 enterprises. But every industry has its top 500.
