They are feed with the alpine snows, lakes and rains of the mountains.
The natural barriers around the Fertile Crescent are the deserts and the mountains.
The people that migrated in the Fertile Crescent, in what is known as Mesopotamia, moved in there because it was the only place that had nice conditions for living and prosper. The Mesopotamia region was between two very big rivers, the Tigris and Euphrates rivers. These two rivers were flooding each year and creating a new very fertile soil, which allowed the people to be engaged in agriculture and have a stable food source, and also to have a stable fresh water source.
On the other hand, the deserts and the mountains, were not providing these condition. The deserts are too dry, there's not enough food and water, and life is extremely hard and has to be in a nomadic style. The mountains are very restrictive in what they offer and in how big of a part of the year. While the summers might be good and provide nice living conditions, the winters are very cruel and can bring death very easily.
Yes, the current American tendency to blame the poor for unfavorable conditions is similar to racist attitudes of the past. Groups in power, whether by class or race, have always tended to attribute their issues to outside parties such as the less-privileged strata of society. For example, Hitler blamed Germany’s post-WWI economic and political suffering on the domestic Jewish population, encouraging the entitled and intolerant “Aryan” Germans. In America today, political groups that are composed of the most-fortunate demographics of society tend to blame the poor for high taxes and invasive social programs. As always, xenophobia against impoverished immigrants prevails and continues to perpetuate the use of “scape-goats” for economic and societal issues brought by other factors.
