If Israel has a working class, it is one of settlers, IDF soldiers, etc. Those are not the "good guys".

There is a longstanding and incorrect view of Western leftists in the capacity of the Israeli working class to build their power and address the injustices. That class has no capacity to do so whatsoever. They are fully bought-off by the ethnocentric project, both materially and psychologically. This is not very different from how other settler colonist "working classes" did the same. If anything, it is an important lesson that the working class is not a moral quantity, it is a group defined by its relation to production, and only through political education can it gain agency for positive change.
