Also, many Jews attained a significant status during the reign of Cyrus and were comfortable there.

After World War I, the Germany economy was in ruins. This is because they were held responsible for the beginning of the war and were forced to pay reparations (as decided in the Treaty of Versailles).
On the other end of the world, the US had a booming economy right after World War I. The 1920's in the US was an era of economic prosperity in which individuals had more disposable income to buy goods/materials.
France and Great Britain still remain allies after this war, as they both have a common goal of recovering from the war and ensuring Germany does not gain significant political power.
