A few things I’d disagree with, Joseph wasn’t accruing wealth for himself, his status was a reflection of Pharaoh. And he clearly overestimates the number of Jews in many nations, but in those days how do you count those things. It’s an excellent analysis, far ahead of the “civility” of the 20th century.
Joseph, whom I recently taught a Sunday School lesson about, is a fine specimen of humanity considering he was all for serving a nation that feared and hated him. He was also a decent person who lived his values the best he could even though the Egyptians didn’t share them.
