I was going to stop this discussion, but I can't figure out what you're saying. Did you drop an "as" in the first line? As in, it wasn't as difficult (to leave Nazi Germany for Israel) for those (Palestinian or Turkish landowners) whose land it(Israel) had been?

Or are you saying the Palestinians / Turks didn't mind working as laborers after being landowners?????

Or maybe I just can't read. Which is a real possibility.
