Hmmm ...I doubt that some intersections are higher-paying - isn't communism supposed to be all about everyone being equal?
And now that you brought it up, and thinking about it, there probably are intersections that are more favorable to work at than others. But to me the favored ones would be the ones with less traffic - there would be less chance of being run over or injured. In theory, the more dangerous ones should be the higher paying ones.
