Why is the population in America so small?

Most Americans are used to enjoying life, so all kinds of homosexuality, such as Wow, Dink, and so on, spread to China from there. In their minds, there is no need to sow and bring seeds, and their children and grandchildren are full. Moreover, the United States is an immigrant country. Originally, the population base was small, but later it experienced the War of Independence, the Civil War, the Western Development, World War I and World War II. So its population has never been very large. Even if Americans only have children later, the population of each family is quite large.

The United States does not need so-called family planning, because they are vast and sparsely populated.
