In which area of the world were the jews most hated? why were they hated

In Germany. It is difficult to pinpoint one single trigger for Adolf Hitler’s (1889-1945) antisemitism, but three key reasons can be identified: the anti-Jewish climate in pre-war Vienna, Germany’s defeat in the First World War and Hitler’s belief that some races were superior and others inferior. 

Well I would think most mostly in European area
Or... Germany
Hope this helps!!!

Ain the free market economic system the government is hands off from all supply and demand rates
