The Mitzriyim elevated Yosef and provided a haven for Yaakov Avinu.
The Kli Yokor at the end of parashas Vayigash explains that, the reason for the suffering and enslavement was because the Jews forgot an important lesson that must be remembered in diaspora. We must constantly keep in mind that we are strangers in a strange land. Moishe Rabbenu constantly kept this in mind, and therefore the G-d of his father was constantly helping him. This was the lesson that Moshe Rabbeinu wanted to teach us through the naming of his children. The Jews wanted to become part of the Egyptian establishment. They forgot that they came to Egypt just as a temporary dweller, who is fleeing his problems temporarily by escaping to a strange land. They became rich and acquired land. They built on it fancy houses which the Egyptians resented.
