Although the United States is a multi-ethnic immigrant country, why are most of its achievements created by white people?

The earliest immigrants came from Europe, which is the hometown of white people. At that time, the Renaissance was going on in Europe, and the bourgeoisie began to enter the stage. Relatively speaking, white people's thoughts are more advanced than other ethnic groups, and their scientific and cultural concepts are ahead of other ethnic groups in the world at that time. So, from the first time white people immigrated to America, they became the masters of America. Because they are masters, they must have two brushes. White people were established in the United States, with advanced science and technology and advanced finance. An advanced national system has been established, and white immigrants are well-educated advanced citizens. A large number of European skilled workers immigrated to the United States, which enhanced the scientific and technological strength of the United States. In short, because white immigrants first immigrated to the United States, they occupied the dominant position and the highest position in the country.
