The correct answer to this open question is the following.
Unfortunately, this question is incomplete because does not include the policies it is referring to. However, we can comment on the following.
Indeed, there have to be policies aimed to control the growth of the population. Otherwise, the federal government could not keep track of the natalities on a monthly and yearly basis. This control is needed because the government has to be aware of the impact of the number of newborns on public services.
However, all the controls instilled by the government have to be reasonable and respect the human rights of the parents. Nothing has to be imposed that does not respect their rights.
The government expects that parents can be responsible enough to bring the number of children they can take care of. To not compromise the health service industry and the public education system, and other public services.
This correct answer is "popular sovereignty."
This idea of letting territories vote on whether or not they wanted slavery was supposed to be helpful in solving the issue of slavery in the United States. However, this led to terrible violence and bloodshed, especially in Kansas. After Kansas voted to become a slave state, many anti-slavery individuals claimed the election was rigged due voters coming from Missouri to vote in the Kansas election. This resulted in fighting between the two. This period is now known as "Bleeding Kansas." This idea was one of many solutions that failed to solve the issue of slavery in America.
