Enslavement and Oppression are two different concepts. And opression better describes the plight of the Jews from Egypt circa 1430 bc. In fact, Exodus 13:1-16 notes that they left with their livestock. Think slaves would have owned their own oxen, and cattle? I am sure there were slaves, but not totally as a people.
The Jews under Egypt were slaves.
Slaves are oppressed.
The slaves in the US could own their own property, too. They kept their own clothes. The slaves under the Romans could be fairly well off, too, if they were favored.
So some of the Jews had beasts of burden and even gold. Doesn't mean the people as a whole weren't slaves in bondage. If they were free people, they could have implemented free market reforms and sold pharoah the best bricks ever.
And this is enough. I corrected the false statement about the Bible not condemning slavery, so the correctees are resorting to quibbles.
If today's (b)lacks want to become slaves again, and by all indications most of them do, then fine. But I'll not become their slave in return. I owe them nothing and never have.
