The spiritual depravity of Egypt would still be part of us, for we would never have survived as one people capable of receiving God's Torah. The rabbis gave us rather explicit instructions as to how the story of the Exodus should be told in order to maximize our feelings of gratitude and identification with the events being described. And the retelling of those events should be in the form of questions and answers. Even the greatest scholar celebrating the Seder by himself is required to recite the Four Questions, traditionally reserved for the youngest child at the table. To fully appreciate a life of freedom to serve God, we must first experience a cruel and degrading slavery that left us incapable of thinking about anything other than surviving the coming day.
Every question is based on a lack of information or understanding.
Successful teachers know that students absorb knowledge far better if they first sought that knowledge themselves - i.e., if it comes as an answer to a question. OUR ancestors experienced Egypt as one continuous question. Joseph's brothers could not make sense of the behavior of the cruel viceroy who confronted them when they first came to buy grain. Only when Joseph revealed himself did everything become clear. Even Moses asked God why He had treated the nation so badly.
