"it's not "every minority and immigrant group", it's the poor ones."
Except Jews in Europe in the first half of the 20th Century (and in other places and times) were targeted for being poor and being rich.
When they were wealthy they were envied and accused of getting their money through immoral means, like usury and stealing it from their poorer neighbors.
When they were poor they were accused of being dirty, and poor because they were lazy.
And when they were neither rich nor poor, well then they were hated for just being Jews.
Even the ones who had fully assimilated weren't safe, because the racial laws meant that who your ancestors were mattered more than who you were.
