Eugenics supporters aimed to improve the genetic quality of the U.S. population. Briefly describe how this practice was used by different organizations and groups. Make sure to include the anti-immigration groups and the Race Betterment Foundation.

Eugenics supporters aimed to improve the genetic quality of the U.S. population by advocating for policies and practices that promoted selective breeding and sterilization of individuals deemed to have undesirable traits. This practice was used by different organizations and groups in various ways.

One of the most prominent uses of eugenics was by anti-immigration groups, who used the ideology to argue for restrictions on immigration from certain countries or regions. They believed that certain immigrant groups carried undesirable genetic traits and would lower the genetic quality of the U.S. population. This led to the implementation of immigration quotas and discriminatory policies targeting specific ethnic and racial groups.

The Race Betterment Foundation, founded in 1914, was a prominent organization that promoted eugenics and aimed to improve the genetic quality of the human race. They advocated for the sterilization of individuals with perceived genetic defects and promoted the idea of "better breeding" to improve the overall genetic makeup of the population. The foundation also supported research and education on eugenics and played a significant role in shaping public opinion on the topic.

Overall, eugenics was used by various organizations and groups to justify discriminatory policies, promote selective breeding, and advocate for the sterilization of individuals deemed to have undesirable genetic traits. These practices had a significant impact on immigration policies and the treatment of marginalized communities in the U.S. and have since been widely discredited and condemned.
