Why didn't America experience feudal society?

The history of America is still very short. This is a country of immigrants. The so-called immigrant countries are all Europe, mainly Britain. Buying and selling blacks is a product of capitalism. At that time, Europe was already capitalist, so it became a country after moving here. Capitalist countries, of course.

In fact, the key lies in your American standards. If you define the United States as a political concept, then it has obviously never experienced a feudal society, because the United States was founded more than 200 years ago. At that time, Americans started a vigorous anti-colonial war just because they wanted to develop their own capitalism.
