No offense, but are you one of these people for whom "not getting lynched" is a "privilege"? If not, then what actual privilege(s) do you have in mind, that Polish jews would have but no other Poles?
Autonomy with regards to administration and official recognition, where in other parts of Europe they were chased away?
When referring to medieval times "privilege" in context of laws has bit different meaning than today.
"...mainly followed in the tolerant policy of his father and also granted autonomy to the Jews in the matter of communal administration and laid the foundation for the power of the Qahal, or autonomous Jewish community."
I stand corrected, I was not aware of that point.
pretty sure it was meant "privileges compared to other countries" and not privileged compared to Poles
