Why did Einstein, a German, switch to American scientific construction?

Speaking of Einstein, we can use an old saying of China to describe it, that is, there has never been anyone, and there is only one person in the world. He is a Jewish physicist. Yes, he is a Jew, not an American as everyone thinks. Einstein gave up Germany twice, which caused quite a stir since then. Why did Einstein immigrate to the United States twice to contribute to American science?

Einstein abandoned Germany twice. The first time he gave up, he didn't like German education, because Einstein was a man who advocated freedom. But the lack of education in Germany turned man into a machine, so he chose to come to the United States to seek freedom, but later he returned to Germany. Later 1933, after Hitler came to power, Einstein chose to immigrate to the United States again. This time, his choice was spurned by the world, because when the country needed him, he chose to give up, which triggered the world earthquake.

In fact, Einstein immigrated to the United States not because of his subjective choice, but because of necessity. Everyone knows that Einstein's contribution is great. He immigrated from Germany to Gome just as the Vatican immigrated to the New World. This is really a big deal. Einstein should be a national treasure for any country, and he couldn't wait to give it up. However, after Hitler came to power, Einstein hated Jews. Because of Einstein's Jewish identity, I'm afraid he can't escape into the gas chamber unless he leaves.

Hitler persecuted Jews, and the world is still outraged. If Germany wants to grow and develop, it must search for rich Jews and even claim that Jews are German vampires. As a great scientist, Einstein did not receive special treatment from Hitler. Instead, he was called "the number one reactionary" and even described Einstein's achievements as "Jewish physics", no matter in Germany, so Einstein was really forced to immigrate to the United States.

When Einstein immigrated to the United States, Hitler boasted that Einstein was a successful "academic scum" spurned by the Germans. So, it's not that Americans have given Einstein much benefit, but that Germany simply can't tolerate Einstein. So Einstein immigrated to the United States twice just to find a foothold, even if he was accused of treason. You may not believe this reason, but it is. In fact, it wasn't the United States that gave him much benefit, just finding a place to live.

In the United States, Einstein has a relatively stable environment, which can better carry out scientific creation, thus making great contributions to the scientific cause of the United States.
