the importance of Jewish trade or industry in Polish economy both before, during and after partitions...second half of the seventeenth century concentrated in the eastern part of the commonwealth...in the eighteenth century...blah blah blah
Okay, so you find one author who wrote about something happening centuries ago and benefiting only some levels of society in some parts of Poland.
Yeah, nice try.
But let's accept your example as if it is all the proof that is needed.
If the Jews and the Jews alone made Poland so strong and prosperous then why were any partitions attempted and successful?
What more should the Jews have done to ensure Poland was never partitioned?
After all, as "integral parts" of Poland's history, they do hold equally responsibility for the partitions happening. Right?
