Because he seen opportunity for expanding his empire
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.
During Sherman's march to the sea he burned and destroyed a lot of Georgia's buildings and farmlands so they would be out of food and materials and would have to give up on the war in order to rebuild
Farmers were probably the hardest hit group of people during the Great Depression. They were already having a tough time from the 1920's because during WWl, they had been making record numbers of crops that were being sent over seas, but once the war ended they ended up with a surplus which dropped the price of wheat and farmers could hardly make a living. Farmers had also bought tractors and farm equipment with an installment plan, which means they buy now and pay later. This caused many farmers to go into debt because once the depression hit they no longer could afford to pay them off. To make matters worse, unsafe farming practices, like not rotating crops, cause the top soil to blow off and huge dust storms, called the Dust Bowl occurred making life miserable for farmers and their families.
