From lectures that I’ve heard by scholars of Ancient Egypt, U.S.-style plantation slavery was not common in that society. A person referred to as a “slave” in Ancient Egypt may simply have been subject to paying a 20 percent income tax, for example, that “free” citizens were not subject to.
As noted in Wikipedia, there is minimal support for the historical truth of the Exodus story in the (otherwise excellent) written records of Ancient Egypt.
Suppose that Jews were indeed once “slaves” in Egypt, i.e., subject to higher-than-usual taxes. How would they be doing in modern times? PwC says that Egypt has a personal income tax rate that tops out at 22.5 percent. Compare to Israel at 50 percent and the U.S. at potentially over 50 percent (broken up into 37 percent federal and 13.3 California state income tax, for example).
Is this sort of like the founding myth of the U.S.? We tell K-12 children in our government-run schools that we started at war against Great Britain because of cruel and high taxation yet now the UK has lower taxes than the U.S. in a lot of areas, e.g., for entrepreneurs whose total tax bill of 10 percent in the UK will be lower than their state tax bill alone in California.
Oh yes, as long as we’re talking about Britain and Passover, as the Labour Party would say… “Happy Passover to readers who are practicing Jewcraft!”
