Under the Influence

Europe's Jewish population has dropped 60% in last 50 years

To describe Yaakov's departure from Be'er Sheva the Torah uses the word VaYetzei. Rashi famously comments that a tzaddik's departure makes and impact as he takes with him the beauty, glory, and luster of the place. When Avrohom left his father's house it says "Lech Licha", why did it not say VaYeitzei?

The Chassam Sofer answers that Yaakov left a city steeped in Torah and Yiras Shamayim that were the hallmarks of all those that came far and wide to be under the influence of Avrohom and Yitzchok. These good people appreciated Yaakov and therefore his departure was a blow to the entire atmosphere of the city. However when Avrohom left his city, it was almost entirely under the influence of Nimrod and his heretical beliefs. Avrohom was a pariah. Therefore his leaving did not impact anyone in the city. In fact they were quite happy to see him go.
