The landmark case Plessey v. Ferguson was significant because "<span>It showed that racial segregation was constitutional</span>" since this remained the case until Brown vs. Board of Education overturned it.
Hamilton thought more about the business side of things and preferred a strong central government formed by an elite class of people while Jefferson did everything for the people and their interest and preferred a strong state and local government formed by the common people. so it was basically Hamilton and the federalists vs Jefferson and the democratic republicans.
the U.S. should not have helped Germany recover from war.
Einstein primarily emigrated to the United States because he had a Jewish background, and Adolf Hitler, who became Germany's chancellor in 1932, was about to adopt Anti-Semitic policies.
It was a very hard choice for Einstein to choose to emigrate to the United States, but it was a very wise one. As a Jew, he knew what was gonna happen if he stayed in the United States. You may already know that the Holocaust happened a few years later, in which most Jews living in countries occupied by Germany were murdered. Thanks to moving to the U.S, Einstein was safe from this event.
