@yatchi and it's a geniusly evil system too. They basically imported workers through the Aliyah concept who are terrified to not support those in power and the way of things through propaganda; and then created through apartheid an even lower class of invisible worker than that (Palestinian Israeli residents) who can be doubly exploited thanks to the fear keeping the other workers in check.
It's horrible and inhumane and generates a lotta $$$$
